To know oneself, one should assert oneself.

I can, therefore I am.

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

Either you run the day or the day runs you.

Quality is not an act, it is a habit.

The secret of getting ahead is getting started.

It's always too early to quit.

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

Be gentle to all and stern with yourself.
