Be gentle to all and stern with yourself.

Begin to be now what you will be hereafter.

Know or listen to those who know.

If you think you can do it, you can.

The secret of getting ahead is getting started.

What you do today can improve all your tomorrows.

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

Well done is better than well said.

To know oneself, one should assert oneself.
