My own diary. It's like debugging a server log of your mind. Note that I quickly deviated from any expected norms of "dear diary, today _____ happened and it made me feel ______", and instead simply decided to write, whatever cames to my mind, every day, no matter how nonsensical. Most of it is pointless and cringe, but there's some brilliant opinions, descriptions of values, and even poetry in there. A diary is, after all, literally an expansion of your mind into the physical realm.
