Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

It's always too early to quit.

Quality is not an act, it is a habit.

Begin to be now what you will be hereafter.

I can, therefore I am.

If you can dream it, you can do it.

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