Dunno if it's really thought-terminating. I mean consider Warren Buffett who has gone with a simple strategy of valuing businesses and buying them or parts of them for less than they are worth or buying two dollar bills for a dollar as he put it. There's a lot of thought underlying that though because then you have to understand businesses and as those interact with everything in the world there's understanding that too. So it's simple in some ways and not in others. But it worked well - I think he'd be the world's richest if he hadn't given a load away to charity.
