Curate, connect, and discover
Hey, friends with poor memory. This is a sign to go ahead and learn anything you want, even if you're afraid you're going to forget it all. Read Wikipedia articles, watch documentaries, take free classes, and delve deep into books and lore. Maybe I'm the only one who has this fear, maybe not. But learning for pleasure is just as much--if not moreso-- about the joy of the experience as it is about memorization.
