This book is a must-read. It shows how to reach your full potential, succeed in your goals, and above all, how to overcome Resistance with a capital 'R'. You can read more about it at Amazon, but I wanted to mention it today because for 10/20 and 10/21/2010, he is selling the ePub or PDF version of the book for $1.99. Pressfield is a prolific and engrossing author and I think he's just dipping his toe into the ebook stream to test the waters.

Even if you miss the sale, it's a great book!
