A great read for this is "Avoid Cognitive Distortions (Hack 58)" in O'Reilly's "Mind Performance Hacks" book: http://oreilly.com/catalog/9780596101534/

There's too much to quote here, but the basic premise is:

Learn to avoid 15 mental mistakes that distort your emotions and further distort your thinking

Hmm, I'll have to dig out the Oreilly Brain Hacks, see what was there
