By failing to prepare, you are preparing to fail.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
Be gentle to all and stern with yourself.
To be a good loser is to learn how to win.
Do not weep do not wax indignant. Understand.
Be thine own palace, or the world's thy jail.
If you've got a talent, protect it.
Never complain and never explain.
Be kind whenever possible. It is always possible.
I never travel without my sketch book.
