What you do today can improve all your tomorrows.

Well done is better than well said.

Be gentle to all and stern with yourself.

If you're going through hell, keep going.

Never complain and never explain.

Without hard work, nothing grows but weeds.

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

To know oneself, one should assert oneself.

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