If you don’t make mistakes, you are not wise; you are a fool.

The fool thinks he is wise and the wise thinks he is not a fool.

When the fool knows when to be silent, he would be sitting among the wise.

A mistake doesn’t make you a fool, but denying it surely makes you one.

A fool’s excuse is always bigger than the mistake he made.

The more mistakes you make, the fewer mistakes are left have to be made.
