Some people are planners; some people are improvisers. It’s a spectrum, of course, rather than a binary, but that’s a basic metric.
I’m an improviser through and through. That means that when unexpected things happen, I’m really good at rolling with it and adjusting on the fly. The bad side is that lots of unexpected things happen! My brother, though, is a very extreme planner. That means he avoids lots of unexpected things. On the other hand, when unexpected things do happen (and at least some of them are inevitable), he gets pretty bent out of shape. Pros/cons either way, and no way is “right.”
