I don't give a shit about my grades, but I still go to class and work hard because I want to learn more. I want to be the best. This is because, ultimately, my success in the startup world will depend on what I learn. But I may be an exception.
But I may be an exception You're not the only one, buddy.
When I was a kid-nerd, adults would ask me what I would like to do when grown-up. You know, in the manner they do this to be polite. And I figured, when I respond "I want to go to university and study!" they would smile and be happy. So there I had my slogan. Thing was: I also meant it. I imagined a place where I could work on projects of my own choosing as opposed to the stuff the teacher would come up with. That's what I thought means "to study". You are completely free, choose your subject and fight to master it and achieve great things that are a blessing for humanity. Oh, well.
