I like competition. I like the reason and meaning it gives to an activity. I like the added pressure to perform. If I lose I learn a lesson. If I win I celebrate. There is just a complexity to it that I find mentally and physically enjoyable. In my life I've competed at things recreationally or socially but also "for real". What's the difference? Social or recreation competition is between friends or family, is ad hoc, has no larger organization behind it and likely didn't cost much money to make possible. Examples would be board and video games, who can do the most push ups, local 5k races, most things that are "I bet you..." or "Let's see who can...". Those sorts of things. While the "for real" type of competition is against others trained in the same thing, is scheduled, has a larger organization involved and likely cost some money to be involved. School sports, sports leagues, things with a ranking system are good examples...
