I can, therefore I am.

Well done is better than well said.

If you think you can do it, you can.

Do not weep do not wax indignant. Understand.

Problems are not stop signs, they are guidelines.

To know oneself, one should assert oneself.

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

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

If you're going through hell, keep going.
