I can, therefore I am.

Never complain and never explain.

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

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

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

Either you run the day or the day runs you.

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

Things do not happen. Things are made to happen.
