Without hard work, nothing grows but weeds.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

Always desire to learn something useful.

Quality is not an act, it is a habit.

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

Do not weep do not wax indignant. Understand.

The secret of getting ahead is getting started.

I can, therefore I am.
