Be gentle to all and stern with yourself.

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

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

Expect problems and eat them for breakfast.

To know oneself, one should assert oneself.

Things do not happen. Things are made to happen.

Begin to be now what you will be hereafter.

The secret of getting ahead is getting started.

If you're going through hell, keep going.
