Be gentle to all and stern with yourself.

Quality is not an act, it is a habit.

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

If you've got a talent, protect it.

It's always too early to quit.

To know oneself, one should assert oneself.

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

Begin to be now what you will be hereafter.

Always desire to learn something useful.
