I can, therefore I am.

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

You never know what motivates you.

If you think you can do it, you can.

Never complain and never explain.

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

Well done is better than well said.

To know oneself, one should assert oneself.

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