My schizophrenic uncle, who I hadn’t seen for a few years, went off his meds and randomly showed up at our house on Christmas morning. He brought me a book wrapped in a brown paper bag. It was Chaos by James Gleick (science and philosophy of chaos theory). I was 9.
I don’t organize it. I page through my kindle library til I find something that appeals to me at that moment. Figuring out a thing to read has never been a problem for me!
