A nation which does not remember what it was yesterday, does not know what it is today, nor what it is trying to do. We are trying to do a futile thing if we do not know where we came from or what we have been about.
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!
