What's more important though is not going around insisting that you are smarter than everyone else. Aside from that being an ideal way to get your butt kicked, it's the first and foremost sign of an ignorant person. Ignorant people always assume everyone else is ignorant. They don't know any better.

Some of the smartest and most talented people on this planet make huge achievements even before they go to college or without ever going to college. Going to college is not a sign of intelligence. Intelligence is something you are simply born with and then, it is nurtured.
