Criticism, like rain, should be gentle enough to nourish a man's growth without destroying his roots. Frank A. Clark
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. Winston Churchill
The trite saying that honesty is the best policy has met with the just criticism that honesty is not policy. The real honest man is honest from conviction of what is right, not from policy. Robert E. Lee

This lends more credibility by driving traffic. Timothy Ferriss
