To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

Do not weep do not wax indignant. Understand.

Things do not happen. Things are made to happen.

If you're going through hell, keep going.

Expect problems and eat them for breakfast.

Be kind whenever possible. It is always possible.

It's always too early to quit.

Well done is better than well said.
