The greatest griefs are those we cause ourselves.

Only people who are capable of loving strongly can also suffer great sorrow, but this same necessity of loving serves to counteract their grief and heals them.

The past has no power to stop you from being present now. Only your grievance about the past can do that.

Life is thickly sown with thorns, and I know no other remedy than to pass quickly through them. The longer we dwell on our misfortunes, the greater is their power to harm us.

Any man can make mistakes, but only an idiot persists in his error.

You will make all kinds of mistakes; but as long as you are generous and true, and also fierce, you cannot hurt the world or even seriously distress her.

Do not be embarrassed by your mistakes. Nothing can teach us better than our understanding of them. This is one of the best ways of self-education.

Be bold. If you're going to make an error, make a doozy, and don't be afraid to hit the ball.
