Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

I can, therefore I am.

The secret of getting ahead is getting started.

Always desire to learn something useful.

Quality is not an act, it is a habit.

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

Begin to be now what you will be hereafter.

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