That's exactly why I was asking the question. When I compete in a sport, my goal is to enjoy myself... and to win. It's not about being arrogant, being vain... And if I lose, I am a good loser and I have no problem admitting my opponent is better than me. But on the other hand, my goal is to win, still. So since you want to win, there will always be a part of you that wants to glorify yourself, right ? So wanting to win, in itself, I feel like it's a sin. And it's not just in sports, but in anything actually. I feel like wanting to be good at something is a sin, because I don't see any way of wanting to have any kind of talent without having any form of pride. I feel like anything I do is a sin, except when I spend time with God and serve Him.
