The Power of Now by Eckhart Tolle - inspirationally simple when read, amazingly hard to do - staying present in each moment. Oh, how the mind does wander away from the present moment! A lifetime of study in one book. You won't wear out its message. I just bought the 52 inspiration cards to keep with me at all times.
The New Psycho-Cybnernetics by Maxwell Maltz and Dan S. Kennedy - an updated, 42-year old classic, still great, and the book that other methods have incorporated from. Self-image is everything!
