We assume stress comes from the size of the job. It doesn't — it comes from how much thinking is running while you do the job. Same role, same demands, radically different levels of stress, depending only on what's happening in someone's head.

Two leaders can carry the exact same workload — one burns out, the other doesn't. The difference was never the hours. It's how much of their thinking was spent resisting the hours instead of simply doing the work in front of them.

Our physical, mental and spiritual wellbeing are the most important elements of our leadership. And yet, we put them at risk every time we prioritize our to do list over everything else.
