What you do today can improve all your tomorrows.

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

To know oneself, one should assert oneself.

Expect problems and eat them for breakfast.

Either you run the day or the day runs you.

Be gentle to all and stern with yourself.

It's always too early to quit.

Without hard work, nothing grows but weeds.

Well done is better than well said.
