It's often better to segregate creative and inhibitive systems even if you need the inhibitive systems to produce a finished work. There's a (probably apocryphal) conversation between George RR Martin and Stephen King that goes something like:
GRRM: How do you write so many books?... Don't you ever spend hours staring at the page, agonizing over which of two words to use, and asking 'am I actually any good at this?'
SK: Of course! But not when I'm writing.
