There is a great service called DailyLit that will email you small parts of a book every day. For those of us who don't have time to sit down and read a book, having 3-4 paragraphs show up in your email makes it easy to fit it into your day. After all, some of us spend 2-3 hours a day in email... why not spend 5-10 minutes reading something truly useful.

Right now I am reading P.T. Barnum's book, "The Art of Money Getting". The title alone makes it worth reading, and the fact its by Mr. "There's a sucker born every minute" P.T. Barnum.
