[Question] Self-education best practices

I have a degree in a field I no longer wish to pursue in my career (English literature). Without a university and all it comes with (libraries, knowledgeable people, etc.), what are the best ways to self-educate and gain a substantive knowledge base in subjects I have little background in, specifically law, philosophy of language, intellectual property, and ethics? I am looking both for specific book recommendations and tips on how to most productively make my way through the material. I am no longer a student, but I have enough time on my hands to do nearly the amount of “course-work” I was doing in college. Also, are there folks who have covered self-education best practices in a book, podcast, etc? I have listened to Tyler Cowen interview Nassim Taleb on this; are there others offering insight on self-education?
