There's an interesting paradox that all chess players experience at some point or another. I love to win, but more often than not, winning a game doesn't make me a better player: I was merely able to out-think my opponent. On the other hand, losing games makes me want to quit playing, because it's not fun to watch my rating drop. But these are the best times to learn from my mistakes and to grow as a chess player. Even the best players lose games! So if you're winning every game you play, you need to find more skilled opponents. The moral of the story is: play for fun, but also play to improve your game!
