The opposite of winning is learning. Or, at least, it should be.
Winning is great fun, but none of us get to win all the time.
Losing can be, and often is, quite painful. But, it's rarely fatal.
Each time we win, we should be thankful (graciously so). Each time we lose, we should think deeply about what we've learned from the experience that will help us get back into the win column the next time around.
Oh, and one more thing: The opposite of learning ....... is losing.
