Make only big mistakes.

The difference between greatness and mediocrity is often how an individual views a mistake.

I am humble enough to recognize that I have made mistakes, but politically astute enough to know that I have forgotten what they are.

If you board the wrong train, it is no use running along the corridor in the other direction.

Give me a fruitful error any time, full of seeds, bursting with its own corrections. You can keep your sterile truth for yourself.

One day when I was studying with Schoenberg, he pointed out the eraser on his pencil and said, 'This end is more important than the other.' After twenty years I learned to write directly in ink.

Allowing an unimportant mistake to pass without comment is a wonderful social grace.

One makes mistakes: that is life. But it is never quite a mistake to have loved.

We do not err because truth is difficult to see. It is visible at a glance. We err because this is more comfortable.

Most of the major mistakes I made in my life, I made when I was too tired to know what I was doing - both personally and professionally.
