Perfection is such a nuisance that I often regret having cured myself of using tobacco.

It's not evil that's ruining the earth, but mediocrity. The crime is not that Nero played while Rome burned, but that he played badly.

I never realized how mediocre the world was until I got involved with some of its supposedly top people.

Sometimes I worry about being a success in a mediocre world.

The indefatigable pursuit of an unattainable perfection, even though it consists in nothing more than the pounding of an old piano, is alone what gives meaning to our life on this unavailing star.

It is only imperfection that complains of what is imperfect. The more perfect we are the more gentle and quiet we become towards the defects of others.

In our corrupted state, common weaknesses and defects contribute more towards the reconciling us to one another than all the precepts of the philosophers and divines.

There is a crack in everything God has made.

Practice does not make perfect. Perfect practice makes perfect.
