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.
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.
Take all reasonable advantage of that which the present may offer you. It is the only time which is ours. Yesterday is buried forever, and to-morrow we may never see.
The body loaded by the excess of yesterday, depresses the mind also, and fixes to the ground this particle of divine breath.
[Lat., Quin corpus onustum
Hesternis vitiis, animum quoque praegravat una
Atque affigit humo divinae particulam aurae.]
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.
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!
..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.
[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.
