>But I felt guilty for not learning new things and just listening to music all day long
Along the same lines something I regularly hear "I don't read fiction it's a waste of time". You can learn new things by listening to music, by doing or engaging with art, by rereading the same stories, and so on. Learning means expanding the mind of the learner, it is not external fact gathering. You can do the same thing over and over and learn something new every time, Nabokov used to (cheekily) point out that the only good reader is a re-reader, because you can only memorize ten books or so, you just gotta find the right ones and they'll last you a lifetime or put more succintly:
"The real voyage of discovery consists, not in seeking new landscapes, but in having new eyes"
