What you do today can improve all your tomorrows.

I can, therefore I am.

By failing to prepare, you are preparing to fail.

Be gentle to all and stern with yourself.

Be thine own palace, or the world's thy jail.

Know or listen to those who know.

Well done is better than well said.

To know oneself, one should assert oneself.

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