You can’t nurture others optimally unless you are nourished yourself. Unfortunately, those who regularly give to others are often the last to give to themselves.
There comes a time when you simply can’t do it all yourself—and you don’t have to. Friends, relatives, and neighbors are usually glad to help out in a pinch. You can return the favor at a later date. If necessary, hire the help you need: home healthcare services, lawn maintenance, housecleaning, or whatever. Set priorities, and let others handle the rest.
