Authentic happiness

is an excellent book by Martin Seligman (isbn 1-85788-329-2). As usual I'm going to quote from a few pages:

Daddy, do you remember before my fifth birthday? From when I was three until when I was five, I was a whiner. I whined every day. On my fifth birthday, I decided I wasn't going to whine any more. That was the hardest thing I've ever done. And if I can stop whining, you can stop being such a grouch.

All emotions about the past are completely driven by thinking and interpretation.

There are, however, no known ways to enhance forgetting and suppressing of memory directly. Indeed explicit attempts to suppress thoughts will backfire and increase the likelihood of imagining the forbidden object.

If you think about bad things in terms of "always" and "never" and abiding traits, you have a permanent, pessimistic style.

Learned optimism… is about accuracy.

Almost nothing that happens to you has just one cause.

Mindful attention to the present occurs much more readily in a slow state of mind.

Total immersion, in fact, blocks consciousness, and emotions are completely absent.

The mood state Americans are in, on average, when watching television is mildly depressed.

The overarching principle of good listening is validation.

By encouraging cheap success, it produced a generation of very expensive failures.

Every drug that breaks up depression also blocks dreaming.
