Be gentle to all and stern with yourself.

You never know what motivates you.

To know oneself, one should assert oneself.

Be thine own palace, or the world's thy jail.

Well done is better than well said.

To be a good loser is to learn how to win.

Go for it now. The future is promised to no one.

The wise does at once what the fool does at last.

Be kind whenever possible. It is always possible.
