There's a great CBT-based book, Authentic Happiness, with a lot of practical guides to disputing negative thought patterns.
In addition, he talks about activities that actually create "flow" in our lives, and build from our strengths. CBT, he points out, is great at getting us from -5 to level ground. But, what about getting people from 0 to +5? His point is that a new science, positive psychology, needs to bridge the gap from curing depression to actually flourishing and becoming happy. Great book.
Oh yes...and try desire lists. See if that works for you.
