It's good to learn from your mistakes. It's better to learn from other people's mistakes.

Men are wise in proportion, not to their experience, but to their capacity for experience.

I've never made a mistake. I've only learned from experience.

Experience is the only teacher we have. We may talk and reason all our lives, but we shall not understand a word of truth until we experience it ourselves.

The people who were trying to make this world worse are not taking the day off. Why should I?

A learned man is honoured by the people.A learned man commands respect everywhere for his learning. Indeed, learning is honoured everywhere.
