Here is a great short article by Max Nisen which encapsulates the wisdom of 15 classic business books in one sentence each. Superficial? Certainly but there is a large element of truth in each concise summary – and it does save you a lot of time.
Incidentally you can save time reading most self-help and positive thinking books. My summary is that nearly all of them are based on one powerful truth – change your attitude and you can change your life.
