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.
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.
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.
..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 never felt so fervently thankful, so soothed, so tranquil, so filled with the blessed peace, as I did yesterday when I learned that Michael Angelo was dead.
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.
What we are today comes from our thoughts of yesterday, and our present thoughts build our life of tomorrow: our life is the creation of our mind. If a man speaks or acts with an impure mind, suffering will follow him as the wheel of the cart follows the beast that draws the cart. If a man speaks or acts with a pure mind, joy follows him as his own shadow.
[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.
