The Antidote

I don't think I'd go that far: I don't hate positive thinking. Nevertheless, Burkeman takes a close look at what science has discovered about positive thinking and, though I hate to smash your rose-colored glasses, it is really not pretty. Positive thinking can lead to some pretty negative thinking. Oddly.

So Burkeman takes another approach. It's to face reality. To look at it carefully. But dispassionately. Realistically.
I like this. It seems a little silly to go around saying, “Life just gets better and better every live long day.” Sometimes, frankly, it doesn't. And it doesn't do any good to walk around, saying it, shouting it, with your fingers in your ears, honestly.

Take a look at this book. It's a hard cold look at happiness. That just might make you much happier.
