I do it with drawing too. I've been doing a lot of sketches geared toward playing with expressions lately. Somewhere along the way, I became convinced I needed to draw things in some undefined "right way" (not life drawing, purely comic) and that's been interesting.
Unwinding it has been fun, though.
I am jealous of your powers. Overthinking is my special skill, but often it results in just not being able to get something done...or only being able to blitz through it (minimal edits to avoid getting trapped) which leaves me something far less refined than the amount of thought I dumped into it would suggest.
