I have a very bad brain, logseq helps me answer things i would not be able like when was the last time I've seen someone, what are my most frequented places so I can easily recommend when someone asks, know if I already watched a move before renting it or get nearby concerts so I can plan the weekend before it's too late, quickly find tickets i bought half year ago, how much money did I spent the past trip, and all kind of personal information. all in a single place, just one Ctrl-k away. I only store personal info, no blog posts, technical notes or work stuff.
