He only moves toward the perfection of his art whose criticism surpasses his achievement.

I want no criticism of America at my table. The Americans criticize themselves more than enough.

Criticism may not be agreeable but it is necessary. It fulfils the same function as pain in the human body. It calls attention to an unhealthy state of things.

Criticism in the body politic is like pain in the human body. It is not pleasant, but where would the body be without it?

I stopped hating and started just being. My whole life, I had been the most defensive person you'd meet, unable to tolerate any criticism. But now I started listening and being.

Ignore all hatred and criticism. Live for what you create, and die protecting it.
