Be kind whenever possible. It is always possible.

Be gentle to all and stern with yourself.

Without hard work, nothing grows but weeds.

Know or listen to those who know.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.

If you've got a talent, protect it.

What you do today can improve all your tomorrows.

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