I can, therefore I am.

To know oneself, one should assert oneself.

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.

Who seeks shall find.

Go for it now. The future is promised to no one.

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

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