Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.

Always desire to learn something useful.

It's always too early to quit.

By failing to prepare, you are preparing to fail.

If you think you can do it, you can.

To know oneself, one should assert oneself.

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

If you're going through hell, keep going.
