Why Do I Need a Proposal for Writing a Non-Fiction Book?

"I’m Bobbi Linkemer on behalf of expertvillage.com, and I’d like to invite you to visit my website at writeanonfictionbook.com. I’ve had clients and I’ve had students who have balked at the idea of writing a proposal. I don’t need it; I’m self publishing; I’m going with print on demand; It’s just amazing. If you haven’t done it, you’re probably going to wish you had. How later on they need something that they didn’t write. For instance, I have a client who needs a title for his book. The book is written, we just haven’t been able to come up with a title. We found someone who is a title expert, and what do you know, she wants a concept statement. We never wrote the concept statement because we never wrote the proposal because we went directly to writing the book."
