I'm not the guy you're asking, but I've spent some time 'in solitude' studying without an academic institution. I'd read philosophy books whenever I have down time. Consciously replacing entertainment with books works as well.
Philosophy to me is less about studying philosophy itself as a topic but encountering different people's various personal philosophies about things. Kierkegaard's "The Present Age" and Glenn Gould's perspective on anxiety helped me a lot.
