the idea that every waking moment in our lives should be guided by one top-level goal is an idealized extreme that may not be desirable even for the grittiest of us. Still, I would argue that it’s possible to pare down long lists of mid-level and low-level work goals according to how they serve a goal of supreme importance. And I think one top-level professional goal, rather than any other number, is ideal. In sum, the more unified, aligned, and coordinated our goal hierarchies, the better.
