Eat That Frog!: 21 Great Ways to Stop Procrastinating and Get More Done in Less Time by Brian Tracy

This is a short, simple motivational book.
It basically recommends that you write lists, prioritize, do the most difficult tasks first, do your best, and be positive. And, the author managed to fill up over 100 pages with that, have it published, and sell it! That is success. It is a simple, quick read.
