"To avoid criticism, do nothing, say nothing, be nothing."

That is impossible. It is like saying if you don't want inhale toxic gasses stop breathing. Youd have to become a rock to avoid critisizm. I'd never do that because I don't care about criticizm anyway.

Rocks aren't that bad actually. You can through them at people. You could adopt one as a pet for yourself. Rocks never complain if you don't feed them, and they'll survive almost anywhere. Just don't throw them in a pound because they'll sink. You can also skip rocks if you want to.
