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!
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.
[T]omorrow is a new day. You shall begin it well & serenely, & with too high a spirit to be cumbered with your old nonsense. This day ... is too dear with its hopes & invitations to waste a moment on the rotten yesterdays.
It was but yesterday I thought myself a fragment quivering without rhythm in the sphere of life. Now I know that I am the sphere, and all life in rhythmic fragments moves within me.
