I've never spoken to anyone, anywhere who had an issue with not working hard enough. And if I did, I would admire them for it, because it takes more focus to hang loose than get swept up in the hustle.
Any endeavor takes effort - from drinking water to following through on a project - but effort can be loving and incremental. That's sustainability. Consistently infusing nurture in all that we do so we can keep doing it - with presence and grace and excitement.
Serving the world, is giving ourselves what we need—often & unrelenting.
