Just because a Jewish nerd with a seemingly scary hair-do said this, it doesn’t necessarily become untrue.
On a personal note, insanity is worth pondering. Like when you know you are not talented and there are certificates to prove it, and you still persistently make elaborate plans to get over it. Like the economist who interprets and interprets knowing fully that he cannot predict a thing, but still makes elaborate plans to ride over it. Like the retail investor who systematically invests all his savings into a market, knowing fully that when the meltdown comes he’s neither a bull nor a bear but a pig, which gets slaughtered – but still makes elaborate plans to average out.
Insanity makes you immobile and wandering at the same time, cluttered and focussed at the same time – like nothing else matters and with no idea how much this thing in hand matters. Like you do the same thing again and again and expect different results. Insanity can be controlled but as Hulk said, once you are in it, you just don’t want to control it, but quit it. And one day the glass ceiling may break, the dead weight on the shoulders may shift – but it doesn’t sufficiently prove that insanity makes sense.
One day you get the load off a bit.
One day the market beats all expectations and surge 800 points; if you have a dog in this, you are certain to expect.
But neither of this proves that insanity has a point. Perhaps the point is to wait till the elaborate plans end. Like to wait till chapter seventy two of book four when Sancho Panza and Don Quixote gets home.
