I try to alternate books I'm reading between fun fiction to business and sometimes even some history. I usually have two or three books I'm in the middle of at any given time. I love a good Nelson Demille or Lee Child novel but usually guilt myself into reading two business books per month under the theory that we all have something we could learn.
The latest business book I finished is Topgrading for Sales. If you have anything to do with a sales organization; whether it's hiring, firing, motivating, or evaluating; this is an absoulte must read. Most business books feel they need to stretch the 4 or 5 points they want to make into 500 mind numbing pages of personal anecdotes. Thankfully this book has gone with the no BS approach. It's 112 pages long and almost immediately gets to the point which is, finding great sales people is tough and if you don't have a systematic approach of building a great team, you will have an average sales team. It's chock full of real exercises that are really eye opening.
