What is the difference between creative professionals and creative entrepreneurs?
My new book will explore the difference between a creative endeavor (a profession that is creative by nature, such as an architect, or a musician) and a profession done creatively. I will argue that any profession can be done creatively, but some lend themselves to creativity more than others.I guess you'll have to read my book "How to be creative in a nutshell" to find out the answer to these and other interesting questions.
