John McEnroe...was arguably the best serve-and-volley man of all time, but then McEnroe was an exception to pretty much every predictive norm there was. At his peak (say 1980 to 1984), he was the greatest tennis player who ever lived-the most talented, the most beautiful, the most tormented: a genius. For me, watching McEnroe don a blue polyester blazer and do stiff lame truistic color commentary for TV is like watching Faulkner do a Gap ad.

You have wondered, perhaps, why all real accountants wear hats? They are today's cowboys. As will you be. Riding the American range. Riding herd on the unending torrent of financial data. The eddies, cataracts, arranged variations, fractious minutiae. You order the data, shepherd it, direct its flow, lead it where it's needed ... You deal in facts, gentlemen, for which there has been a market since man first crept from the primeval slurry.

I felt despair. The word’s overused and banalified now, despair, but it’s a serious word, and I’m using it seriously. For me it denotes a simple admixture — a weird yearning for death combined with a crushing sense of my own smallness and futility that presents as a fear of death. It’s maybe close to what people call dread or angst. But it’s not these things, quite. It’s more like wanting to die in order to escape the unbearable feeling of becoming aware that I’m small and weak and selfish and going without any doubt at all to die. It’s wanting to jump overboard.

The capital-T Truth is about life BEFORE death. It is about the real value of a real education, which has almost nothing to do with knowledge, and everything to do with simple awareness; awareness of what is so real and essential, so hidden in plain sight all around us, all the time, that we have to keep reminding ourselves over and over: "This is water." "This is water." It is unimaginably hard to do this, to stay conscious and alive in the adult world day in and day out.

The real irony is that the view of infinity as some forbidden zone or road to insanity - which view was very old and powerful and haunted math for 2000+ years - is precisely what Cantor's own work overturned. Saying that infinity drove Cantor mad is sort of like mourning St. George's loss to the dragon: it's not only wrong but insulting.

the psychological need to believe that others take you as seriously as you take yourself. There is nothing particularly wrong with it, as psychological needs go, but yet of course we should always remember that a deep need for anything from other people makes us easy pickings.

Learning how to think really means learning how to exercise some control over how and what you think. It means being conscious and aware enough to choose what you pay attention to and to choose how you construct meaning from experience. Because if you cannot or will not exercise this kind of choice in adult life, you will be totally hosed.
