Seest thou how pale the sated guest rises from supper, where the appetite is puzzled with varieties? The body, too, burdened with I yesterday's excess, weighs down the soul, and fixes to the earth this particle of the divine essence.
You have it now and that is all your whole life is; now. There is nothing else than now. There is neither yesterday, certainly, nor is there any tomorrow.
So yesterday you fell off the wagon? Or maybe you blew your diet? Or lost your temper and shot off your mouth? Well, that was yesterday. Today is a brand-new day with a clean slate, so forget yesterday!
It is not enough to want to make the effort and to say we'll make the effort. We must actually make the effort. It's in the doing, not just the thinking, that we accomplish our goals. If we constantly put our goals off, we will never see them fulfilled. Someone put it this way: Live only for tomorrow, and you will have a lot of empty yesterdays today.
