The way you describe it, he kind of sounds like a person with Aspergers with business as his special interest.
Not saying that's what's going on. I don't know much about Buffet, but it sounds like some people with Aspergers I know that have other interests (mainly science).
Personally, reading about the same thing 8 hours a day sounds like a dream job to me.
Warren Buffet is an outlier among outliers. Clearly there are things anyone can pick up from his approach. I think I'd struggle to keep everything in my memory :-) but I think there is a lot to say about the kind of knowledge that one should seek to acquire. On reading I read also on Farnham Street that Charlie Munger reads quite broadly I wonder if it is the same with Mr Buffet
Same here, my memory is one of my worst attributes. If you ask me about tasks I've done last week, I might have trouble remembering them (or any details) without looking up Jiras.
I get the argument of compounding knowledge, though. It should still apply to someone with bad memory. For instance, if I know that I'll be switching my career in about 3-5 years, won't I throw away a great deal of my knowledge and skills? Why do something like this in the first place? This goes in the same direction as focusing yourself on one thing and one thing only (in your career).
