What makes people do what they do?

I believe that people are, at some level, insecure about themselves. Humans are naturally born to be social. People tend to have the idea that they must be a certain way to liked by others. Even though people do their best to live up to the social standard, there will always be that idea that there will always be someone achieving that standard better than them. This makes people feel almost worthless. This puts people in a position where they feel they have to know that someone is doing even worse at achieving the “standard” so they know that there is someone that is “lesser” than themselves. This puts people at ease knowing that they are not the furthest away from the standard. So the first thing people do when they meet someone else is look for a quality that the other person doesn’t have.
