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.
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.
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.
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.
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.
