Without hard work, nothing grows but weeds.

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

Never complain and never explain.

To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

You never know what motivates you.

What you do today can improve all your tomorrows.

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

The dog that trots about finds a bone.
