If you win and it creates or encourages hubris, the long term value of that win is often negative.
If you lose and learn, using the loss as a springboard to accelerate improvement; the long term value of that defeat is positive.
Champions often blend the two perfectly.
Winning, with humility.
Winning, but with the focused self-criticism of a motivated loser.
Never satisfied.
Judging success not only by the immediate victory but on the endless quest to improve.
