I learned a lot myself, but lately I just can't make it on stable regime because you don't get much positive feedback you you're learning something yourself. There's no grades, no exams and all of your motivation is internal. In that case you need to work on a motivation and goals. Why would you learn something that doesn't pays off then?
To improve your life, circumatances, abilities. To have a larger amount of known concepts to connect to each other. To increase your stability, security, quality of life, and self reliance. To make more money. To decrease your reliance on uncontrollable and unstable factors.

I'm quite fortunate to keep piling on knowledge without extrinsic rewards: the acquisition itself and the rewiring of my brain is what makes it enjoyable for me.
I look up to people who are well-read and try to follow their example. Maybe one day I can inspire somebody else.
