Early on I just read books and built distributed systems and database engines from scratch.
These days I have been able to drink from the firehose on YouTube for a variety of subjects. Physics, chemistry, business finance, technical analysis (stocks), CAM, food production, and plenty more. I'm literally blown away at how much more efficient it is than trudging through college. If you put in the work you can go deep and gain skills very quickly.
