Except for some effects that I attribute mostly to age, my intuitive thinking is just as prone to overconfidence, extreme predictions, and the planning fallacy as it was before I made a study of these issues.

We think of our future as anticipated memories.

The planning fallacy is that you make a plan, which is usually a best-case scenario. Then you assume that the outcome will follow your plan, even when you should know better.

We don't see very far in the future, we are very focused on one idea at a time, one problem at a time, and all these are incompatible with rationality as economic theory assumes it.

People are constantly clamoring for the joy of life. As for me, I find the joy of life in the hard and cruel battle of life - to learn something is a joy to me.

Happiness is not merely a word. It is a state of mind.

I have never had a current state of mind. My mind changes a great deal. I am very affected by any sorrow or sad thing, and I am very affected by joy and beauty.

I love the show 'It's Always Sunny in Philadelphia;' that's probably a guilty pleasure! I laugh so hard.
