Years ago we used a simple picture in our leadership programmes: the human battery. It has a capacity, it charges, it runs down, and sometimes it leaks. The leak is the part we find most interesting. It's the unresolved conflict, the decision you keep reopening, the email you've read fifteen times and still not answered. None of it looks like work, yet it drains you all the same. We dust the model off, along with the Harvard Business Review line we used to hand out, that energy rather than time is what performance really runs on.
We talk about how the physical, mental, emotional and spiritual batteries pull on each other. A hard gym session after a day of vibe coding leaves the body tired and the head clear. The end of summer comes as a relief to two introverts who have been out and about for weeks. We compare our own leaks, from a nagging injury to 3 a.m. wake-ups to grief after losing a close friend, and own up to our "false friends": the glass of wine, the chocolate, the Netflix evening that feels like rest but doesn't top anything up. Spiritual energy turns out to be the one we're least sure about, and possibly a blind spot. We finish with a small habit worth trying: ask yourself how charged you are when you wake up, check again later in the day, and let that answer, rather than the gaps in your calendar, decide what you say yes to.
