As long as you still have one bridge left, nothing is lost. But from the moment that you cannot even understand the storytelling or the music of other cultures anymore, then we become strangers to each other and the situation will become very complicated.
What could be more advantageous in an intellectual contest - whether it be chess, bridge, or stock selection - than to have opponents who have been taught that thinking is a waste of energy?
When you build a bridge, you insist that it can carry 30,000 pounds, but you only drive 10,000-pound trucks across it. And that same principle works in investing.
Crowds stand around all day long and criticise that bridge, and find fault with it, and tell with unlimited frankness how it ought to have been planned, and how they would have built it had the city granted them the $14,000 it cost. It is really refreshing to hang around these and listen to them. A foreigner would come to the conclusion that all America was composed of inspired professional bridge builders.
To go out of your mind once a day is tremendously important, because by going out of your mind you come to your senses. And if you stay in your mind all of the time, you are over rational, in other words you are like a very rigid bridge which because it has no give; no craziness in it, is going to be blown down by the first hurricane.

If you understood a business perfectly and the future of the business, you would need very little in the way of a margin of safety. So, the more vulnerable the business is, assuming you still want to invest in it, the larger margin of safety you'd need. If you're driving a truck across a bridge that says it holds 10,000 pounds and you've got a 9,800 pound vehicle, if the bridge is 6 inches above the crevice it covers, you may feel okay, but if it's over the Grand Canyon, you may feel you want a little larger margin of safety.
Building new roads and bridges creates jobs. Growing our exports creates jobs. Reforming our outdated tax system and our broken immigration system creates jobs.
The thing I'd really like to see is the old London Bridge, with all the old buildings around it like Shakespeare's Globe. I'd like to walk along that. Don't worry, I won't get drunk and fall in.
