Instructions of King Cormac, King of Cashel
Be not too wise, nor too foolish
Be not too conceited, nor diffident
Be not too haughty, nor too humble
Be not too talkative, nor too silent
Be not too hard, nor too feeble.
If you be too wise, men will expect too much of you
If you be too foolish, you will be deceived
If you be conceited, you will be thought difficult
If you be too humble, you will be without honour
If you be too talkative, you will not be heeded
If you be silent, you will not be regarded
If you be too hard, you will be broken
If you be too feeble, you will be crushed.
