I know myself pretty well - or at least I thought I did. I seem to know exactly what I'm doing somewhere inside me, even if at the time I feel like I have no clue. I've sabatauged myself in a very percise manner. I knew I would try to give up and give in, but knowing that I would I had to do something to prevent it. So I set myself up. I made sure I had no money, no credit cards, no stable place to stay, I left myself with NO easy options other than finishing my book and having it be a sucess. It's never really been that I've lacked or had confidence in myself as much as having confidence in what i've found and the book I could write about it. It was kinda like a "If you build it they will come" type of thing but "if you write it they will read"
