No nation can rise to its full moral maturity so long as it subjects a segment of its citizenry on the basis of race or color.

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

Criticism is easy; achievement is difficult.

I'm not everybody's cup of tea. But sometimes criticism can be hurtful. Be respectful I'm a good piano player, I can sing well, I write good songs. If you don't like it, fair enough. But give me a break.

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.

Maturity is often more absurd than youth and very frequently is most unjust to youth.
