Very interesting topic!
I don't think of myself as a perfectionist, but sometimes I find my ambitions exceeding my patience. I seem to be better at taking on and planning projects. I get all fired up, make preparations, and gradually lose interest. I do finish things... eventually, but at my age, I'm almost certain to run out of time before I run out of projects. I think that if I relaxed my standards a bit, I would accomplish more.
