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.
With the mistake your life goes in reverse. Now you can see exactly what you did Wrong yesterday and wrong the day before And each mistake leads back to something worse.
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!
[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.
But our minds are bound to the yardstick of yesterday, today and tomorrow, and with that yardstick we try to inquire into the unknown, to measure that which is not measurable.
..there is nothing worse than the feeling that no one cares whether we exist or not, that no one is interested in what we have to say about life, and that the world can continue turning without our awkward presence. I began to imagine how many millions of people were, at that moment, feeling utterly useless and wretched—however rich, charming, and delightful they might be—because they were alone that night, as they were yesterday, and as they might well be tomorrow.
I have got this letter which actually goes out the day after I die. It has already been written. And it says that: "Yesterday I died". And then it says: "That's bad news for me, but it's not bad news for you, the shareholders of Berkshire". And then I go on and explain what is going to happen. I know that is one time when they will be really interested in hearing from me.
