Good stuff! You make me look like a dilettante, which has more than a grain of truth. I read/look at something that catches my fancy, for the sheer joy, follow until I feel I have got a good 'feel' for the subject/wider context and move onto my next whim. I suppose at my age (62) I no longer have the dedication that I once had. When I did there were only books and magazines, no internet then. Keep it up.
