[@andersonarigoni284]

I think it's because you didn't watch it because someone was telling you to watch it. You watch it because you and only you found it interesting and clicked to watch it/continued to watch it. That's the problem with our educational system: we are not free to learn what we find appealing. We're not incentivated to look for what interest us. We're forced to seek knowledge that doesn't correspond to what we desire. We will keep thinking school is boring while they keep pushing things that are not of our desire in our heads. We need to be able to choose what we want to learn, not something that other person thinks it will fit us.

[@-loarado]

@@andersonarigoni284 This is very true but at the same time I still don't think the education system will change at least in the US for a long while, maybe even not in our lifetimes, because it's very hard to just change the entire system all over the country. It will take a long time, maybe even school by school.
