I have never met someone who enjoyed schooling that I would see as interesting. Adversity breeds invention, and one needs to invent the self in order to find who they are. You are not born with a personality, but it is created in a curiously fateful way. We are born with genes that give us talents, impact behavior, intelligence, and a physical state. Likewise, your environment is the creation of your parents genes in the places you live, the food you eat, and the experiences you have had. We are a combination of nature and nurture.
The introvert is part of you as well. You are a fourth generation introvert as far as I know. The introvert will not make you the life of the party or the popular boy. Both of you are terribly handsome and intelligent, yet that is not what makes someone popular. Good looks are necessary but the other is a charisma that can be stupid and cruel. How do these people become popular you may ask? The popular kids speak to the lowest sense of ourselves.
There is a part of everyone that likes to see someone have a bad day. We like to see someone fall, especially if we did not when we approached that spot. It is part of the basic human condition to elevate oneself by debasing others. Popularity and the win is all relative and that is why the popular are not extraordinary individuals. They simply know how to debase everyone else around them. Their extroversion and stupidity help as they can loudly protest your worth as their feeble minds can.
You are not wrong in hearing my own debasement of their character and worth; nobody is perfect. I have lived through the torments and issues that meekness will provide a man. That is why you were always taught to step forward. The safest way through is at the head even if it is against your instincts. If you cannot make it to the head, at least try to land mid pack.
Popularity breeds in itself the mundane. It is with adversity that we come to invent and in the process build our story. The cruel of this world is what builds heroes. Keep that in mind as you build yourself. If you accomplished something, what was it that inspired you? Did you move in spite of that voice that told you not to? That is where growth happens. It is slow and painful, yet should be steady and celebrated. Never stop finding your next adversity.
