The book presents an interesting viewpoint on the meaning of life, questioning traditional self-help gurus, consumerism, and over-obsession with positive thinking.

The book talks about randomness, associated maths, and the psychological biases which interfere with a more stochastic approach to thinking about life.

Java has fewer quirks compared to C++, but sometimes I do come across surprises. A code like following will fail to compile since you are trying to initialize a variable with an uninitialized variable. Java 1 2 3 4 5 6 7 8 9 public class Sample { private final String mField1; private final String mField2 = mField1 + " two"; private Sample(String field1) { mField1 = field1; } } But if instead of directly referencing mField1, you reference indirectly via a getter method code will compile, and mField2 will get null value for mField1. ...

Day 1 We started our journey with Templo Mayor, a 700-year-old Aztec temple, and took a guided tour of it. The ticket to the temple costs MXN 70 per person, and the guided tour in English was for MXN 300. It takes about 3-4 hours to explore the archeological remains and the museum. I would recommend this museum over other archeological museums in the Mexico city since this one had descriptions written in English. ...

The book provides a scientific perspective on the history of how humans came to dominate the planet. The book’s biggest focus is on the three revolutions the cognitive revolution which started 70, 000 years ago; the agricultural revolution which started 12, 000 years ago; and the scientific revolution which started 500 years ago and shaped the destiny of our species and the planet.

The common belief is that in the case of perfect competition (“commoditized goods”), buyers will always buy the lowest priced item, and this will dwindle down profits to practically nothing, and that’s why it’s called red ocean in the first place. While this is true in general, there is at least one notable exception to it. Consider the example of toothpaste, in the US, a toothpaste is ~1-2$ a piece. Are buyers really going to buy a white Colgate for 10¢ lower price over a red Colgate? Most would just stick to whatever they are used to. And that’s where lies the real strategy if the good’s price is an tiny fraction of the budget, it might never get optimized on. ...

The book talks about Martin’s experience as a brand consultant where he tries to expose the subtleties of marketing used by corporations to create or increase demand for their products. Some techniques mentioned in the book are morally questionable. Overall, it’s a great read into at the intersection of psychology and business. I would recommend reading this in conjunction with " Influence: The Psychology of Persuasion".

The Island of Hawai’i, popularly known as the Big Island, is the biggest island in Hawai’i. Unlike other islands, this one is too big for driving around with mopeds. The island has two cities at the two corners, Kona and Hilo. If you are a coffee lover then you would note that Kona indeed is the source of Kona coffee. Day 1 Flew into Kona late night and drove directly to Holo Holo Inn. It’s a beautiful rustic place to stay next to the Hawai’i Volcanoes National Park. The park had an active volcano till 2013. Now, only the dried magma is left. The petroglyphs are good, but nothing worth spending too much time on. ...

Shops love selling them since the margins are great, the local government loves them since it brings in additional tax revenue, and the tourists love them since they don’t want local bacteria to interfere with their enjoyment of authentic experiences. Mother nature pays the price. It’s a classic example of negative externality where the local businesses, the local government, and the tourists get a perceived benefit at the expense of the environment. ...
