Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

It's always too early to quit.

Things do not happen. Things are made to happen.

Never complain and never explain.

Do not weep do not wax indignant. Understand.

Either you run the day or the day runs you.

If you're going through hell, keep going.

Be kind whenever possible. It is always possible.
