It is ironic: people don’t notice that noticing is important! Or that they’re already doing it. It’s kind of like breathing—we’re not usually that aware of it. It’s much easier to recognize more “outbound” activities like brainstorming, testing, designing, refining. But noticing is just as important—it’s really where everything begins. There’s a funny Zen saying about that: “Don’t just do something, sit there.” It’s a reminder to let yourself take things in as well as output them.
