At the moment I am a high-performing computer science student. I also operate a rapid prototyping company with which I provide 3D modeling, 3D printing, electronics rigging, and app development services. I taught myself most of the business, programming, and engineering skills I use to provide my services. I wouldn't say I am successful (yet), but I'm absolutely more capable and accomplished than many of the unremarkables who squander their existence.
What's my point? Society can suck a dick. As long as you never allow your passion for learning to be extinguished you will live an accomplished life. I won't candy coat it; several subjects were nightmares for me. Studying them was worth it though, because I gained an understanding of the world many people will never have. Society is mostly comprised of unremarkable people, and if you suffer through the inevitable agony you will accomplish things they never will.
When I was your age two pieces of literature had a huge impact on the way I think about myself. "Self-Reliance" by Ralph Waldo Emerson, and "The Alchemist" by Paulo Coelho. (There are free PDF version of "The Alchemist" if you search for them through Google)
Below is my favorite passage from "Self-Reliance". It's my favorite quote. It makes me feel okay about the inconsistency of my mind.
"A foolish consistency is the hobgoblin of little minds, adored by little statesmen and philosophers and divines. With consistency a great soul has simply nothing to do. He may as well concern himself with his shadow on the wall. Speak what you think now in hard words, and to-morrow speak what to-morrow thinks in hard words again, though it contradict every thing you said to-day. — 'Ah, so you shall be sure to be misunderstood.' — Is it so bad, then, to be misunderstood? Pythagoras was misunderstood, and Socrates, and Jesus, and Luther, and Copernicus, and Galileo, and Newton, and every pure and wise spirit that ever took flesh. To be great is to be misunderstood."
And here is an off-topic Teddy Roosevelt quote. This is my second favorite quote. I read it every time I fail after exerting .
"It is not the critic who counts; not the man who points out how the strong man stumbles, or where the doer of deeds could have done them better. The credit belongs to the man who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again, because there is no effort without error and shortcoming; but who does actually strive to do the deeds; who knows great enthusiasms, the great devotions; who spends himself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if he fails, at least fails while daring greatly, so that his place shall never be with those cold and timid souls who neither know victory nor defeat."
Maybe those two pieces of literature and/or those two quotes will motivate you in some meaningful way like they motivate me.
And sorry for the long reply.
