The Gorilla Study refers to an earlier research project by Chabris and Simons revealing that people who are focused on one thing can easily overlook something else


Questioning what we believe and want is difficult at the best of times, and especially difficult when we most need to do it, but we can benefit from the informed opinions of others.

The inherent complexity of a software system is related to the problem it is trying to solve. The actual complexity is related to the size and structure of the software system as actually built. The difference is a measure of the inability to match the solution to the problem.

Start over somewhere else

In 1960, the revolutionary regime in Cuba illegally confiscated all the Bacardi company’s Cuban assets without compensation and forced them out of the country. The Bacardis lost their business and their home, but as history has proven, not their spirit. They simply started over somewhere else.


On working for your dreams

We must always remain conscious of the difference between working toward our dreams and working for other people. Other people will fire you.

Money Vs. Happiness

Some of our cultural wisdom about happiness looks suspiciously like a super-replicating false belief. Consider money. If you’ve ever tried to sell anything, then you probably tried to sell it for as much as you possibly could, and other people probably tried to buy it for as little as they possibly could. All the parties involved in the transaction assumed that they would be better off if they ended up with more money rather than less, and this assumption is the bedrock of our economic behavior. Yet, it has far fewer scientific facts to substantiate it than you might expect.

Economists and psychologists have spent decades studying the relation between wealth and happiness, and they have generally concluded that wealth increases human happiness when it lifts people out of abject poverty and into the middle class but that it does little to increase happiness thereafter.

Americans who earn $50,000 per year are much happier than those who earn $10,000 per year, but Americans who earn $5 million per year are not much happier than those who earn $100,000 per year. People who live in poor nations are much less happy than people who live in moderately wealthy nations, but people who live in moderately wealthy nations are not much less happy than people who live in extremely wealthy nations. Economists explain that wealth has “declining marginal utility,” which is a fancy way of saying that it hurts to be hungry, cold, sick, tired, and scared, but once you’ve bought your way out of these burdens, the rest of your money is an increasingly useless pile of paper.

remarkably smart computer

The three-and-a-half-pound meat loaf between our ears is not a simple recording device but a remarkably smart computer that gathers information, makes shrewd judgments and even shrewder guesses, and offers us its best interpretation of the way things are.

Because those interpretations are usually so good, because they usually bear such a striking resemblance to the world as it is actually constituted, we do not realize that we are seeing an interpretation. Instead, we feel as though we are sitting comfortably inside our heads, looking out through the clear glass windshield of our eyes, watching the world as it truly is.

We tend to forget that our brains are talented forgers, weaving a tapestry of memory and perception whose detail is so compelling that its inauthenticity is rarely detected. In a sense, each of us is a counterfeiter who prints phony dollar bills and then happily accepts them for payment, unaware that he is both the perpetrator and victim of a well-orchestrated fraud.

Excerpt from Stumbling on Happiness by Daniel Gilbert


The prefrontal lobe is a part of our brain that helps us think and make decisions. It's located at the front of our head, right behind our forehead. It's like the "control center" for our thoughts and actions, and it helps us plan things, pay attention, and solve problems.
