To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

Well done is better than well said.

Be kind whenever possible. It is always possible.

Do not weep do not wax indignant. Understand.

I can, therefore I am.

The most effective way to do it, is to do it.

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