I am extremely competitive. If I can't be No. 1 I would rather not even try. I have a Sag Sun, Gemini Moon and Gemini Asc, none of which are especially known for competitiveness. I have nothing in Leo and Aries. However, I do have Mars conj Jupiter and Mars square Sun (and a very loose Mars square Moon) and I think that's the source of the problem...I also have Mars semisquare Pluto. The thing is not many people know how competitive I am (just the people closest to me). I am very good at hiding it, and most people think of me as sweet I guess. I guess that's the effect of Venus trine Mars and Jupiter and Moon opposition Neptune and Sun in 7th...Anyway, Leo and Aries may be more upfront about it, but those with the right aspects can be just as competitive, though not in an obvious way.
