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

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.

After a storm comes a calm.

Know or listen to those who know.

Quality is not an act, it is a habit.

I can, therefore I am.

To know oneself, one should assert oneself.
