In other words, you can't get it right until you don't care if you get it wrong.

Perfectionism is the great killer of creativity. Creativity is messy. The final polished product belies all the scribbled mistakes that went before it. No shortcuts here. If we can't accept that, we'll create nothing.
Nothing worthwhile anyway.
