Not everyone has this drive to learn different things. To be honest, I don't have it that much either. It's just a lot worse for me to not do anything. I get too bored and then everything goes downhill.
Some YouTube tutorials are boring, even though useful, but others are actually fun to watch. The channel CrashCourse has great courses on a lot of topics explained in simple ways and with cool animations, and channels such as Kurzgesagt approach very interesting topics with really well done and great looking animations.
The fact that such videos are also short is a bonus. You learn something new, and it's fun to watch them, because they're like educational cartoons sometimes, without having to sit for hours staring at your screen.
