11. Keep a travelogue
See those people? The one in the center, (blue shirt) he’s from (or lives in, at least,) Montana. He’s on a 6+ month vacation after saving up.
He’s going to buy a motorcycle in Vietnam and go on from there. Do I remember his name? Nope. Not in the least. And I’m not going to remember because I (idiotically) didn’t keep a travelogue.
