Could you clarify your question a bit, onthegomom? I'm not sure if you're asking about intensity in general or about aggressiveness in particular.
Intensity in general is, I think, an attribute of giftedness (though it's certainly not confined to the gifted population!!).
I think that intensity can be good and bad: it's good because it can drive someone to do something new or difficult. It can also feed into persistence in the face of adversity. It can be bad if there aren't any controls on it and the person goes too far without realizing it's time to quit.
So the thing that makes it good can also make it bad.
Our house is full of intensity. Even the cats are intense around here. I mean, someone could probably feed the power grid off the intensity in this place, if only they could hook us up.
