Add to the list Profit First by Mike Michalowicz.
The Pumpkin Plan by Michalowicz is my favorite of his books.
I have a problem staying focused and always want to try to do everything and have as much variety in my business as possible which can be a real negative as it stretches people and resources thin. This book was great for helping me.
Another book along the same lines that I really like is The One Thing by Gary Keller.
