My second prescription for misery is to learn everything you possibly can from your own experience, minimizing what you learn vicariously from the go… - Charlie Munger

Crowd folly, the tendency of humans, under some circumstances, to resemble lemmings, explains much foolish thinking of brilliant men and much foolish behavior.

We all know of individuals, modern Ben Franklins, who have 1) achieved a massive multidisciplinary synthesis with less time in formal education than is now available to our numerous brilliant young, and 2) thus become better performers in their own disciplines, not worse, despite diversion of learning time to matter outside the normal coverage of their own disciplines.

The best antidote to folly from an excess of self-regard is to force yourself to be more objective when you are thinking about yourself, your family and friends, your property, and the value of your past and future activity. This isn't easy to do well and won't work perfectly but it will work much better than simply letting psychological nature take its normal course.
