Currently I'm working my way through John Nunn's book entitled "Winning Quickly at Chess."  It is a book that attempts to demonstrate that many people lose at chess early in the game because of some basic flaws in their thinking.  I'm going through the book at the rate of about one game a day and entering them into Chess base so that I can go back and forth through the variations.

It's an interesting self-assignment.  We'll see if it pays off when I go to play over-the-board or online.
