We don't put first things first to get them done and out of the way - we put them first because of the critical effect they have on everything that follows.
Somehow, when we do what God asks us to do, the best we can, keeping first things first, out time seems to come back to us, added upon and multiplied. It's a miracle.
Whatever it is, figuring out your own best time will save you time. I find that when I'm tired, when my battery is running low, when I'm exhausted and weary, is not a good time to plan because I don't always make my best decisions then. Everything looks bigger and harder.
I'm often extremely busy, and yet I'm wasting time. How about you? Other times I can be relaxing, thinking and feeling, pondering - and I'm using time very, very well! I don't want to mistake busyness for being effective or using time well. More busyness is not evidence that I'm good at using my time.
Let's be supportive and kind to each other because we may be in a different season than our neighbor, our sister, our mother at our age, or whatever. We can't judge each other because we're in different seasons and situations.
We may enjoy a few do-nothing days, but there are no do-nothing seasons.
