Heck yes.
Due to the undeniable fact to which most people who knew me well would agree on, I'm extremely competitive, more so academically than in other activities such as sports, though I tend to maintain the same level of competivity in music and art (painting, sketching, the like.) I've always worked hard to be the top, or at least near the top in every class and when I'm not one of the top two or three in the class I begin to doubt myself more than a little and definitely become jealous of those who are, since I envy their intelligence, which I always seem to consider far above mine, though I hardly ever show it in this case, and it only ever results in me pushing myself harder in order to reclaim my spot at the top. Needless to say, I get jealous of others really easily, except socially, I'm never jealous of the really popular people or anything because I feel that if I were like them, I'd feel really pressured by both my social and academic life. Its not like I'm against having friends and spending time with them, I just would hate to be trapped between friends and school. When music and art is the case I'm quite a bit less competitive, and allow myself to admit that there are thousands of people in the world many times better than me (my violin teacher, for example xD), though in that case I tend to take those people as my inspiration, though when some kid who previously was worse than me (not necessarily by much) suddenly becomes some...star player, or something for lack of a better term, that's when I tend to get jealous of them, and it's not that major, not like it is academically or anything. If anyone, I'm jealous of my friend Alex, who is just about perfect as far as grades and music and art go.
