Am I the only one who feels the opposite? I used to take great care in making plans, knowing what's up ahead, knowing what I should know and so on. Spontaneous moments like "Lets go to X" were very infrequent. Nowadays, as a Proper Adult, I much more like going places without knowing anything about them, with as little plans as possible, figuring out what the place is from the people I meet there, and only start reading about the place once I'm there.
