I don't think it's just this, I wonder if there is maybe a certain genetic factor as well. My anecdote is not data but I know that I left home at 17 with a tank of gas and some clothes and ended up living half a continent away in a totally new situation entirely on my own. I came from a completely stable and supportive home environment, I just wanted some adventure. I don't think I'm the only one with this experience or even particularly rare.

Human communities have always needed a majority of members who are focused on family, community, and stability, but they've needed a minority of members who are more interested in the horizon - these people are the traders, explorers, settlers, etc and I wouldn't be surprised if there is some reproductive advantage (maybe your offspring are more likely to have a diverse genetic composition or something) I wonder whether there might be a genetic contributor toward wanderlust.
