When we put the user at the center, and make them the point of integration, the entire system becomes simpler, more robust, more scalable, and more useful.

Having a lot of work on my plate is fine. Meeting deadlines is fine. Planning long term projects is fine. Debugging code is fine. Writing detailed feedback is fine. Pairing with someone to teach them something is fine (fun even!). Interpersonal conflict is (unexpectedly) mostly fine. It’s when all of these things happen within an afternoon that I find myself reminiscing for the days of silently, calmly designing or coding for 6 hours at a time.
