That's what Sly author and the Pitbull of Personal Developement, Larry Winget would tell you.
I'm currently reading his book Shut Up, Stop Whining & Get A Life! (http://www.amazon.com/gp/redirect.html?ie=UTF8&location=http%3A%2F%2Famazon.com%2Fs%3Furl%3Dsearch-alias%253Daps%26field-keywords%3Dlarry%2Bwinget%26Go.x%3D0%26Go.y%3D0%26Go%3DGo&tag=bestmyspacepr-20&linkCode=ur2&camp=1789&creative=9325) and I'm loving it so far. He's very direct and to the point. Because of this, there isn't any fluff in his book which allows him to cover more material. It also makes if for a quick read!
