Be kind whenever possible. It is always possible.

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

Be gentle to all and stern with yourself.

To know oneself, one should assert oneself.

Know or listen to those who know.

The wise does at once what the fool does at last.

Things do not happen. Things are made to happen.

If you've got a talent, protect it.

Leap, and the net will appear.
