I hear ya. Stupid as this sounds...stick with it.
I have
a friend who is writing her first novel, and she is sticking to a rule whereby she doesn't allow herself to re-read anything she's written prior, until the whole book is at least written in draft. Otherwise she finds herself in constant edit-mode, writing and re-writing old sections instead of writing new stuff, which makes her feel discouraged about the overall progress.
She also doesn't allow anyone else to offer comments, good or bad, until she's ready. So while I have read the book she's working on, I am under strict embargo to not offer any suggestions, or else she will go bananas.
