Glow in the dark
Some people are able to reflect the light that lands on them, to take directions or assets or energy and focus it where it needs to be focused. This is a really valuable skill.
Even more valuable, though, is the person who glows in the dark. Not reflecting energy, but creating it. Not redirecting urgencies but generating them. The glow in the dark colleague is able to restart momentum, even when everyone else is ready to give up.
At the other end of the spectrum (ahem) is the black hole. All the energy and all the urgency merely disappears.
Your glow in the dark colleague knows that recharging is eventually necessary, but for now, it's okay that there's not a lot of light. The glow is enough.
