A few things I have done or are in progress: Changing my preferred technology stack from debian(linux)/java/scala to openbsd/rust, and adding sqlite to my postgresql use. I'm becoming (I think) a better husband & person generally than I used to be (life is about learning, in part).
And a big, very hard one: learning to live (and be a better person) happily and with (a new kind of) balance with Chronic Fatigue Syndrome -- big enforced lifestyle changes there. (Very hopefully I will learn all the lessons I should--if not it would be a major lost opportunity.) My doctor (world-class specialist) says they see a lot of suicides in the field (though to be clear, that is not a plan, threat, nor persistent thought of mine). Life is challenging and good, and I am grateful for very many things.
Edits: My learning style seems generally like sheer persistence, with specifics depending on the subject, often finding the basic/intro materials and working them into my daily/weekly routine somewhere, maybe a few relaxing intro videos or articles on a subject while resting.
Also Esperanto, and improving my limited Russian, with some Soviet movies with English subtitles, and reading the side-by-side text of the Book of Mormon in Russ. & English (it has the Russ. accents marked, to reduce the need to look up words--there is no rule for emphasis like there is in Spanish or Esperanto); the AnkiDroid app helps a lot. I learned to ride a unicycle after 40, not to a high level, but it was still a thrill--every time I could just get on and go down the street was a rush. A talented nephew ignored my "experienced" advice and learned unicycling much faster and better than I, on a 26-inch wheel even. (As you'd guess, there are some people on youtube with amazing skills, like "mountain unicycling" or freewheeling (no pedals) fast downhill.)
For education: If someone is seeking economical, high-quality, online university education (from start to Master's), BYU Pathway Worldwide and/or Western Governors University are impressive options, even if one needs to, for example, learn English and/or study skills in an inexpensive intro program. I and others have commented more about them in prior discussions, w/ more info in wikipedia.
And there are so many more things to learn in the future. I'd love to have some good musical improvisation & sightreading skills; wow.
