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?...

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.

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 the [perceived] benefits at the expense of the environment....

Cities have been central to the human civilization. Their dense population provides a platform for the serendipitous interactions and cross-pollination of ideas from different domains, their abandoned portions provide cost-effective real estate to struggling artists and entrepreneurs, their riches provides jobs, sometimes, side-jobs for the innovators to experiment. No wonder innovation in a city grows super-linearly (~(size)4/3) with its size. But the Internet was supposed to destroy all advantages a city has over the rural areas....

Detroit used to symbolize the prowess of American manufacturing. Foreign delegates would drive or fly to Detroit to see this iconic city. San Francisco Bay area (Silicon Valley) was once called the Detroit of the west, and at that time, it meant admiration. The city has a tumultuous racial history. It’s the only city in the US to be taken over by the Federal army thrice to control riots. Before my visit, I had read the book " Detroit: An American Autopsy", it’s a bit long but gives a thorough understanding of this once iconic city. The city neighborhood looks in the state of somewhat despair, even though the suburbs like Dearborn, where Henry Ford was born, are in much better shape. The motor city is spread out, so don’t leave the airport without renting a car. Another thing that stands out is the sheer number of Arabs and the Arabic language as the second or the third language on the signboards.

The book is rated as the best business book by both Bill Gates and Warren Buffett.

The way the human brain learns is different from how it remembers. Good practitioners know how to remember. Good teachers know how to make others learn.
