According to Wikipedia, Lifelong learning means “ongoing, voluntary, and self-motivated” pursuit of knowledge for either personal or professional reasons.” Voluntary and self-motivated is the key to this learning process. No one should force you. Maybe they can encourage it.
I started as an “Economics” major in university. After the first semester, I felt too much irrelevant mathematics, so I transferred to an “International Relations” degree. I’m glad I made the right choice. My formal learning of Economics ended in 2007. But, I have never feel stranger to the Economics topic. I always like to read and ask myself questions and learn more.
These days, I follow a couple of Youtube Channels and blogs about many topics. My top 5 are Psychology, Art, Finance, Solo-Travel, Investment, and Music. I feel the joy of new learning keeps my mind sharp, and as a reward, I feel I am earning a new “set of eyes.”

They write every day (last 15 years) on their blog also they have online Marginal Revolution University (FREE!) I enrolled already Micro Economics and International Finance Course.
