I'm in the same 150+ group. I really think it doesn't mean much on its own. While I am able to breeze through some things and find some connections sometimes that elude some of the other people, it's not that much different than all the other people doing the same at other occasions. I am still very much average in large majority of every-day activities, held back by childhood experiences, resulting coping mechanisms etc, like we all are.
Learning from experience (hopefully not always your own), working well with others, and being able to persevere when things are tough, demotivational or boring, trumps raw intelligence easily, IMO.
