Gregg Popovich, el sargento de hierro

Llevaba tiempo buscando un libro sobre Popovich, los busqué en inglés, nada, en español, nada. De repente me entero de la existencia de esta publicación, de manera que lo compré de inmediato.

La historia está bien narrada, pero a mi gusto le falta un poco de indagación en aspectos de su vida más cercana. Comprendo que el personaje es hermético, pero creo que para escribir un libro de este calado habría que haber llegado un poco más allá.


Este libro, se puede encontrar en Amazon, si solo aquí, y es la aventura de El Búfalo en su viaje desde Alaska a Nueva York en invierno.

Es un libro divertido de leer y que te lleva a muy buen ritmo a través de sus aventuras.

Si quieres leerlo, antes te recomiendo que veas videos y fotos de sus aventuras. La complejidad de esta aventura es muy alta, y las decisiones que tuvo que tomar fueron a veces dramáticas.


Álvar Núñez Cabeza de Vaca is the main character of this book, which explains in old Spanish, all his adventures in America. The tone of the book is very basic, the stories are brutal and without any “sweeter”.

The way they advanced, the starving periods they suffered, how they engaged with the original people of the places they were…

Hard labor, by Sam Smith

This is a tough book to read, each page is difficult to digest, and every single story is hard to read.

When I read Red and me, I found some hard stories about the racism, the challenges the players were having to dedicate their lives to this sport, etc, etc. Hard labor explains how this happens across the whole country without exception.

Hard Labor: The Battle That Birthed The Billion-Dollar NBA

The whole book goes around the Oscar Robertson’s lawsuit against the NBA that finally made possible the free agency for the NBA players.

The first days of the free agency were not good days, and the players involved in this mechanism were always in trouble.

The suit took 6 years (1970 – 1976) and it blocked the ABA – NBA merge. So you can imagine how Oscar and the other 13 players pushing the NBA as an adversary, so they treated accordingly; not easy days for these players that were spending their savings on attorneys.

The book also covers so many inside stories about the game,

and this is something that makes the book warming about the stories, the personalities of the players, and how the things happened during those days.

Gregorio Hernández Jiménez

ha escrito muchos libros sobre bolsa, este es el segundo que empiezo a leer y el primero que termino, el otro aún lo tengo a medias.

El libro me ha permitido aprender cosas básicas sobre el trading que no sabía, explicación de los indicadores básicos, una guía de como integrar todo y sobre todo unas explicaciones con algunas metáforas muy buenas que son fáciles de recordar.

Todo lo que leí hasta ahora estaba enfocado en trading sobre Forex y cryptomonedas, este está enfocado en stocks, lo cual, combinado con las explicaciones básicas de indicadores me ha resultado muy fructífero en estos momentos.

Thinking basketball

In the back side of the book you can read:

Behavioral economics, traffic paradoxes and other metaphors highlight this though-provoking insight into the NBA and your own thinking.

So I bought the book.

Some remarks to remind

Individual scoring is not replaced, it is redistributed.

Look at the global impact of a player, not just to the score.

Scoring blindness

A tendency to focus on a individual’s scoring while overlooking his other actions that influence the team score.

Individual players are limited in their impact (measured through WOWY (with or without you) method).

Variance, rules of thumb

  1. Low variance is “consistent”
  2. High variance is “inconsistent”
  3. The greater the variance, the larger sampple needed to make accurate conclusions.

Sample size insensitivity

A tendency to consider the given sample as sufficient for reaching a conclusion.

Winning bias

When a team wins, in order to explain why they won, we sift through memories of the positive events in the game. When a team losses, we eximine the negatives. This phenomenom is at the crux of winning bias.

Winning bias: a tendency to overrate how well an individual performed because his team won and underrate how well an individual performed because his team lost.

Winning bias creates a selection filter to find evidence that supports a particular conclusion.

Late game bias

A tendency to incorrectly weigh events as more important the later they occur in the game.

  • Good teams win early.
  • Clutch play matters little.
  • Hero ball and isolation plays are low-efficiency.
  • Good teams and good offenses don’t need to rely on a “closer” while bad clutch teams can be great NBA champions.

All of these beliefs about the importance of crunch-time, for both teams and players, come from late-game bias.

The rings fallacy

The false belief that championship rings in team sports are a relevant determiner of an individual’s performance.

Championship hindsight

The false belief that after a season ends, only the team that won was a “championship” level team.


How well a player’s skill travels to other, retaining value on successful teams. For instance assistants, passings, rim protection…

Lone star illusion

A tendency to cover-credit one player with the majority of a team’s success when there are no other all-stars on the team.


Our mental scoreboards are constructed from heuristics: a way to seek the solution of a problem through non-rigorous methods, such as by trial and error, empirical rules.

Heuristics is basically intuition, guess.

Our heuristics become crutches for our narratives. Over the years we have developed a tendency to focus on individual scoring at the expense of Global Offense or Global Defense contributions.


The book reviews different bias that are present in the way the narratives are done, simplifications are set, etc. To me the explanation of these specific bias and the way the narratives are done is the most valuable learning from the book.


Triggers, creating behavior that lasts

“Triggers” is the name of this book, which goal is:

  • Enable you to create behavior that lasts.
  • Help you to be the person you want to be.

I was reluctanttriggers, creating behaviors that lasts

when I started to read this book, thinking about what it could offer to me.

Marshall Goldsmith does a direct clear introduction about what the book is about and it convinced to me about the idea.

I like the way he express the ideas, the stories and the tone of the book is very pleasant;  somtimes you have the feeling he is coaching you while you are reading it and this interaction is funny too.

What I put in practice

There are several aspects about triggers that are described in the book. I have put some of them in practice:

1. Identification of triggers:

This analysis is very interesting to understand how they happen, how they evolve, and the consequence they produce. Once you have listed the triggers it’s interesting to put on the proposed diagram. The division of the trigger in: event, behavior, consequence; is also an important topic to understand how it works and what you have to change: the behavior.

2. Remove negative things from the environment:

The importance of the environment is something I was understimating. Now just with the analysis of it, and the identification how it influence on me, I pay more attention to this aspect.

3. Save time adding time:

I just added a table on a paper with things I should eliminate and how much time it takes per week. I have been able to earn 12 hours easily for activities that matters to me.

4. “21 days challenge”

As an exercise to promote the addition of good habits in my day to day. I plan to do a couple of these per cycle, increasing the complexity and attending the more important habits I want to incorporate.

5. Daily engaging questions:

I have started to do it, and it’s linked to the previous point of the 21 days. It turns the desire in habits and let me evaluate the situation.

6- The wheel of change:

I have done a list of things, then I have given them an unique number (basically the same list of identified triggers). Finally I have drawn the wheel.

I have added each point:

  • in the place I think it’s today,
  • and with an arrow, to the direction I want it to go. This is helping me to evaluate where I am and where I would like to be.

7. “1 hour questions check”:

This is useful to distress special situation where you know you can easily fall in the wrong behavior.

  • Did I do my best to be happy?
  • Did I do my best to find meaning?
  • Did I do my best to build positive relationships?
  • Did I do my best to be fully engaged?

8. List of depleting activities:

You do the list and then you define a strategy once you are in front of them: delegate, avoid, postpone, just do it… When you have to do then, change your attitude lowering the depleting impact.

9. Good enough attitude:

Avoid the conformist attitude in your personal live.

Be a professional, not an amateur.

the wheel of changeProviding structure and timing

You will find a lot of tips as: do “this” 21 days and you will solve “that”, and some other tips without context. I collect these tips an I quickly relize they are not realistic, they make no sense on the context of the rest of my life, so they are useless without context.

The difference on “Triggers” book is that Marshall provides us 2 important things:

  1. Structure to work on each things you want to change.
  2. Specific activities and exercises with different timings:
    1. 1 hour question check.
    2. Daily questions.
    3. 21 days challenge.

So, if we plan different priorities, start adding them in the loop of changes, puting them in the right timing and driving the things in the right direction; then and only then we can really promote change in the way we behave.

The happiness advantage

Seven principles of positive psycology that fuels success and performance at work, by Shawn Anchor.

The Happiness Advantage

says that people who are happy have a psychological advantage over people who are unhappy. One way to test this is through studies over time.

  • Meditate.
  • Find something to look forward to. Anticipate future rewards lights up the pleasure centers (Pirineos)
  • Commit conscious acts of kindness.
  • Infuse positivity into your surroundings.
  • Exercise.
  • Spend money on activities.
  • Exercise a signature strength (painting…)

The Fulcrum and the Lever

talks about the power of the mindset. The fulcrum is the mindset of the person; the length of the lever corresponds to the potential power and possibility that person believes s/he.

If someone moves the fulcrum in the right direction by adopting a more positive mindset, the lever of possibility lengthens, which leads, to an eventual positive outcome.

The more you believe in your ability to succeed, the more likely it is that you will (confidence).

Remind yourself the relevant skills you have, rather than those you lack.

More important still that believing in your own abilities is believing that you can improve these abilities. Instead of being a “fixed mindset” person, be a “growth mindset” one.

The Tetris Effect

talks about how to retrain your brain to spot patterns of possibility rather than patterns of failure.

The tetris effect stems from a very normal physical process that repeated playing triggersin their brains. They become stuck in something called a “cognitive afterimage”.

Scan the word with positive attitude: it increases creativity, decreases stress and increases our motivation to complete the goals. The result? happiness, gratitude and optimism.

Falling Up

How to find the mental path out of failure.

The Zorro Circle

In the face of overwhelming odds, how to fight off emotions and regain control by beginning with small manageable goals, and them make the circle bigger.

The 20-Second Rule

is about how to fight off the weakening willpower to be positive.

We are mere bundles of habits that we are able to automatically perform many of our daily tasks.

Willpower is not the way, the more you use it, the more worn out it gets. You have to workout your willpower. The need to train the habits (21 days).

Advertisers and marketers make their live on the path of least resistance. They easy the way they want you to act (basically as an illustrated hedonist).

Lower the activation energy for the habits you want to adopt, and raise it for the habits you want to avoid. To decrease the amount of choices also lower the activation energy to act.

Repeated actions is the key to create these habits, until te actions become ingrained in your brain’s neural chemistry. And the key to daily practice is to put your desire as close to the path of least resistance as humanly possible. Identification of the activation energy is a key step on all this.

Save time avoiding distractions and activities that are not a priority.

Set rules of engagement in advance, it free us from the constant use of willpower.

Bolsa para Dummies

Un amigo me recomendó leerme este libro, en concreto la parte 3, que recorre un día de trading cualquiera, repasando hábitos y actividades en las cuales nos deberíamos centrar; y la parte 4, que repasa varias estrategias básicas: gap, bandas de bollinger, y cruce de medias. Me sirvió para confirmar algunas cosas que ya había aprendido y reforzar algunos hábitos.

El libro está escrito en un lenguaje muy directo y repite las cosas varias veces sin resultar demasiado espeso. Se lee rápido y encuadra los conceptos en base a un esquema que se respeta durante todo el libro.
