I receive many emails saying: "I want to be a professional photographer - or at least I'd like to make some money with my hobby. Do you have a book recommendation?"
Here's the book I recommend: Real Magic - Creating Miracles in Everyday Life - by Dr. Wayne Dyer.
It's my favorite self-help book, and it sure helped me! I used to work in an advertising/PR agency in NYC, wearing a suit and tie for 10 years. That was 20 years go.
Check it out. Link at the bottom of my Books page.
While you are there, check out Dr. Zakia's book, too! He is another amazing author.
Best of luck in the new year!
