In Seth Godin's new book, The Icarus Deception: How High Will You Fly? Seth challenges everybody to try and fail. Look for the problems, fix them, then try again and get better. Try again and get better. Try again and get better. It's the only way to ever get good enough at anything.
Seth is an instant jolt of motivation for me. If you don't want to buy the book, check out his blog.
