Human beings are works in progress that mistakenly think they're finished.

I actually think the same things do make most people happy. The differences are extremely small, and around the margins. You like peach ice cream; I like strawberry ice cream. Both of us like ice cream much better than a smack on the head with two-by-four.

I think good things are happening to me and will continue. I am not optimistic about the rest of the species, but I'm so blessed, it's almost scary. I'm sorry to disappoint you, but I have a wildly sunny disposition. I love to laugh.

Most of us appear to believe that we are more athletic, intelligent, organized, ethical, logical, interesting, open-minded, and healthy-not to mention more attractive-than the average person.

We are happy when we have family, we are happy when we have friends and almost all the other things we think make us happy are actually just ways of getting more family and friends.

The good news is that going blind is not going to make you as unhappy as you think it will. The bad news is that winning the lottery will not make you as happy as you expect.

Humans react to danger when it is immediate, immoral, visible... Global warming does not press any of those buttons.
