I can, therefore I am.

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

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

What you do today can improve all your tomorrows.

To know oneself, one should assert oneself.

Well done is better than well said.

If you think you can do it, you can.

Be gentle to all and stern with yourself.

Either you run the day or the day runs you.
