Though I actually am pretty sympathetic to your basic plea here, because the whole reason I started blogging was in an effort to write faster, and critical to that effort is learning to hold your writing to lower standards. . . . (Do not try this with anything other than writing!)

No? Really? I've gotten the idea that you should lower your standards whenever you find yourself simply not doing something. I am pretty bad at drawing, since I've had practically no experience. Recently, therefore, I've figured that I should go ahead and draw something, even though I know that I'll do a bad job of it. I'm sure that Robin Hanson would love pointing out that the fact that a performance is too poor to show to other people doesn't mean that it's too poor to practice privately.
