Marco Arment:

I’m traveling this weekend, and I’ve been doing something I’ve never done: I’ve been using the hotel’s gym. Any Apple Watch owners can probably guess why: I have a good run going on my daily Activity circles, and I want to keep it going.

Apple knows a tremendous amount about user psychology, about what drives people. The fact that Marco feels compelled to keep his exercise streak going, even when he’s on the road, says a lot about the Apple Watch as a health driver and about the genius of those circles, just waiting to be filled.

Ever since getting the Apple Watch, not only have I been getting more consistent exercise, but I’m pushing myself further. I take more walks, and I walk faster and further than ever before. I’ve been walking Hops around the same streets for four years, but now I’ve been discovering new streets and paths just to extend our walking distance and try to beat my previous walks.

I’ve never cared before, but now, I care.

Well said.
