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

Without hard work, nothing grows but weeds.

Be gentle to all and stern with yourself.

If you've got a talent, protect it.

To know oneself, one should assert oneself.

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

I can, therefore I am.

If you think you can do it, you can.

The dog that trots about finds a bone.
