The “turn-key” business you create with Gerber’s model can bring you a profitable practice and a satisfying life.
As you read each of these books, make notes and take from the book what you feel is most important. You won’t agree with everything these authors say, but each has something you can use. Find the kernel of truth in these books and other like them, and incorporate this truth into your startup.
