One of the best insights the book provided me was about positioning yourself in your market. It goes as follow:
“When you’ve identified the market you’ll serve, the next step is to position yourself as the go-to resource in that market. Now before you begin to panic, allow me to tell you something, which I hope will have you breathing an enormous sigh of relief: You don’t have to be the best. All you need to do is to take the value you bring and articulate it in a way that positions you favorably in the eyes of your target prospects.” (Pete Savage, The Wealthy Freelancer)
I found the book very useful for my freelance translator business and will for sure use many of the tips in it. If you go to http://www.thewealthyfreelancer.com/, you can download three chapters for free and see for yourself.
