Be gentle to all and stern with yourself.

It's always too early to quit.

If you think you can do it, you can.

To know oneself, one should assert oneself.

I can, therefore I am.

If you're going through hell, keep going.

Things do not happen. Things are made to happen.

Do not weep do not wax indignant. Understand.

Expect problems and eat them for breakfast.
