writing badly and cringily is actually an essential part of the writing process, both in terms of individual projects and in gaining voice and confidence as a writer in the long term. there is no way around the cringe. there's no way around the work.
You're going to have to do it sooner or later. Do it sooner.
...In the late 1970s, David Gerrold told me, "The first million words are for practice." He was right. This fact won't necessarily stop you from putting some of those first million words out where other people can read them, or even selling them. But you will still be practicing for a good long while.
So make your peace with that, and get busy.
