It's a shame mindfulness has been so secularized and dumbed down and individualized that it's become a meaningless chore (or worse).
Instead of tense, goal oriented mindfulness (a contradiction, actually), letting go of self concern, being present with love, empathy, concern and kindness that SHOWS up in compassionate action, is something that has been recognized around the world for thousands of years as the very essence of true "self care" - self care that makes no fundamental distinction between self and other.
This shows up concretely as supportive families, neighborhoods, communities, cities, towns......
and yes to all who say it's completely insane and deeply pathological that so many of the world's leaders seem to work in the opposite direction - leading to the development of unsupportive neighborhoods, communities, etc.
