I'm human so I'm certainly not immune to social anxiety or embarrassment from looking stupid, but I have been trying to do a manual override that for the last year.
Something it took me an embarrassing amount of time to realize is that the first draft of nearly everything I do is bad. The first draft of my code is usually bad, the first draft of an essay I write is usually bad, the first version of something I draw is usually bad. If I don't allow myself to look stupid, even if only for the first draft of something, then I'll never accomplish anything. Doing something crappy is a means to doing something not-crappy.
I don't think I'm alone with this. There appears to be some ambiguity on who actually first said this, but there's an adage of "There's no great writing, only good rewriting".
