To know oneself, one should assert oneself.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

By failing to prepare, you are preparing to fail.

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

Problems are not stop signs, they are guidelines.

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

Begin to be now what you will be hereafter.

It's always too early to quit.
