The school takes no responsibility of your future! You are fully responsible for your own future! That is why you have to find what you want to do! You are all free!
Don't act because something is interesting, but act because you want to find something more interesting! In this world, there are so much interesting things. Do something that you don't want to do, you don't have even a second for it.
Even if you're not interested, just read my recommendation. Putting aside disliking the food before trying it, I won't forgive you if you dismiss manga without giving it a chance.
Your own feelings are the most important, when it comes to enjoying the interesting things in life. If you just follow what someone else says to do, or just do what you're told, you won't even be able to enjoy the things you like.
Doing something you want, isn't doing something you are good at, nor is it doing something you are able to. If it's to fulfill your wish, even if you're weak in it, you'll do it.
Just because of your angry, childish actions, do you know how many will suffer from it? Don't you go thinking that lives are not connected, you idiotic brat!
Don't think that by abiding the rules you'll automatically be useful to society. Rules are not there for us, they are there for the "person who made it" and the "reality" and "future", which are bound by these lies. They are preventing you from reaching your full potential. Which is why, if there is a future that you want, fight for it! Fight for it and pin down your own "reality".
