You never know what motivates you.

Problems are not stop signs, they are guidelines.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

Know or listen to those who know.

To know oneself, one should assert oneself.

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

If you think you can do it, you can.

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