"… it’s better to work highly focused for short periods of time, with breaks in between, than to be partially focused for long periods of time. Think of it as a sprint, rather than a marathon. You can push yourself to your limits for short periods of time, so long as you have a clear stopping point. And after a rest, you can sprint again."
