Retire
Fill a cup to its brim and it is easily spilled;
Temper a sword to its hardest and it is easily broken;
Amass the greatest treasure and it is easily stolen;
Claim credit and honour and you easily fall;
Retire once your purpose is achieved - this is natural.
-- Lao Tse, "Tao Te Ching"
After all, all he did was string together a lot of old, well-known quotations.
-- H. L. Mencken, on Shakespeare
Hubbard's Law:
Don't take life too seriously; you won't get out of it alive.
