If you need the classic : http://www.amazon.com/dp/0060920432/ Flow:The Psychology of Optimal Experience
This book is not those personal-help books, instead inspires/motivates you to overcome (hacking pseudocode for the layman); if I may compare - very similar to talk about getting over "the wall" by Randy Pausch, but this book gives more insight 'behind-the-scenes'.
