Alright so I do a lot of free writing to get over my writer's block, but sometimes I turn the free writing into a short story. If you were in the middle of a book and you all of a sudden got another idea for a book would you quit the book you were on and start a new one while your mind is on the subject or just overcome your writer's block and go on with the book you were working on? I'm afraid if I start a new one I won't finish the old one. I guess another option is to incorporate the free writing into the book somehow as well. what would your best advice be?
