3 things I loved about Creative, Inc...
Leave the inspiration to someone else. This book tells you how to become a creative freelancer, and spends little time on why. I love that approach, it’s about how hard work works, not about inspiring you to take a leap without a net.
Their resources list in the back of the book will point you toward information for all parts of your freelance experience. From copyright to sole proprietorship you can find answers here.
