I read it in college as a French major. At the time I was a pre med and did not have the wherewithal or organizational habits to make it in med school.
Reading the book was crucial to my success later on.
I still remember his example of the mechanic who lays down everything without a plan but “keeps everything in his head”. He can work wonders but if somebody misplaces one or two of his key tools he is lost.
The “methodical” mechanic seems like he is wasting a lot of time on meaningless categorization, but he will be able to cope with chance occurrences the best.
Gotta go read it again now....
