What motivates people to act?

People act by how they look, how many friends they have, how rich they are. Some people act like there better than others, they try to be funny, try to get attention, and they make fun of kids whose friends with someone that person who is making fun of them doesn't like. Those kinds of people are just losers, and I know two groups of three kids who do just that. Most people are selfish and self-centered since they only care about themselves and not the person next to them! The time I really wanted something was when I was about 11 and I really wanted Guitar Hero for the PS2. I told my parents that I would barely play it even though I loved it so much and was on it all the time. I also told my parents that it'd help for better hand-eye coordination.
