Isn't success when you achieve a goal you set out for yourself? I think it depends on the person and what they wanted out of something. For example, winning or being on top doesn't always mean success because sometimes, the goal for some people is more than those things and those things are not enough. On the other hand, losing and failing can mean success for some people because their goal is to try, get experience and learn. The mindset matters when you try to tackle a goal - do you want to win or do you simple want to try?
