It's a number of years ago I heard a Elizabeth Elliott, say * a woman should learn to delegate any work that a child or helper could do, so she could focus on work only she could do. That made a profound impression on me.In past year or so I've had it come back to my mind a number of times, and more I think on it, wiser that thought appears.
Just think, of all little chores that are part of your basic daily routine. In how many is it conceivable that someone might learn to do that as well, perhaps better, than you?
If you gave up making beds, preparing family's breakfast, and washing dishes, how much free time would you have to do creative writing?
If someone else mowed lawn, swept porch and driveway, watered flowers, could you check on a discouraged friend by phone and lift their spirits? Or create a gift to take to them?
If you've been overwhelmed with far more to do than is humanly possible, maybe it's because you were never meant to do ALL those things. You are hogging work that someone else ought to be doing.
