One of the things that's hardest for me to cope with is being gentle with myself while I'm learning. I expect everything to come quickly and it frustrates me no end when it takes longer than I think it should, especially when I'm doing something creative that I want to look good out of the gate.
Folks call this "permission to suck" but it goes even deeper than that. It's more like "permission to move at your own pace and still suck".
