Be gentle to all and stern with yourself.

What you do today can improve all your tomorrows.

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

To know oneself, one should assert oneself.

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

The secret of getting ahead is getting started.

Be kind whenever possible. It is always possible.

Things do not happen. Things are made to happen.

It's always too early to quit.
