“Never interrupt when you're winning.”
“Never argue when you're winning.”
“It's never just a game when you're winning.”
“You're never as good as everyone tells you when you win, and you're never as bad as they say when you lose.”
“You're never as good as you think you are when you win; and you're never as bad as you feel when you lose.”
“When you're winning, keep working like you're losing.”
