Popular doesn’t mean being wealthy. Popular means, “Has friends”. Having money does not make people popular. It just makes them bait. They are nibbled at by everyone who wishes they could afford that outfit, that car, that stuff. If they hang out skillfully enough, someone with money will let them use some of their stuff. Maybe they will get to be seen riding in that car. Mostly, kids with money hang out together because they know this; maybe straight out, maybe in a corner of their mind. Hanging out with other kids who have money they feel like they are being liked for who they are, not what they have. That may be true in some cases.
When they finish high school, turn eighteen, they are no longer fed by their parents. They have to leave the nest/burrow/den to either live and thrive, or be eaten by predators. Trying to be like them, following them, focusing on them will not make your life a success. What they have in school is their parents’ stuff.
Ignore all that goo gah. Ignore it ALL. You are being like a bird focusing on a shiny object. Look at you. What do you want? No, stop peeking at the shiny stuff. What do you want? Do you want friends? Do you want a pet? Do you want lots of attention? Do you want to be alone to create, and dream, and invent? Do you want good grades?
If you want to have a flock of people around you, you have to realize, only one or two are really your friend, and the rest only want something from you.
Look at animals in the wild. There are herds, which move together, but individually. The only time you see lots of animals flocking to one animal in a hurry is when they are eating it. Be an individual who moves with the herd. Just be. Be strong. Be smart. Be what you are good at.
