Makes sense to me, sketches are both looser and lack the expectation of making it a finished piece, while when you start with the idea/plan of making it a finished/polished piece you have this worry that drives you to make sure the details are going right as you make it and the worry that it could end with an unsatisfying (to you) result. Or at least that's one possibility, I don't know your headspace nor am I a therapist/medical professional of any kind. Just saying what sounds right
