Hi Folks,
Brian Tracy has lots of great material available for free on youtube. Here is one great lecture he gave. If you'd like more from him, at Barnes and Noble I was able to find a 3 disc audiobook called "Goals: How to get everything you want faster than you ever thought possible" for 10 bucks. It's probably the best 10 bucks I ever spent.
