I have flashes of competiveness that can get ugly, but it's a nuanced type. I don't get angry, I get increasingly disappointed at myself for playing/doing badly, until I just become rather dejected. And it's not so much about 'being first', but more, 'not being last'. As long as I'm not the worst at something, I'm fine. But if I'm losing - especially if I'm losing badly, I just get morose.
