In that same article you quote there is also a bit about Feynman, that "Richard Feynman was fond of giving the following advice on how to be a genius. You have to keep a dozen of your favorite problems constantly present in your mind, although by and large they will lay in a dormant state. Every time you hear or read a new trick or a new result, test it against each of your twelve problems to see whether it helps. Every once in a while there will be a hit, and people will say: "How did he do it? He must be a genius!" " I've come across this before, but it got reversed in my mind to: every time you come across an unsolved problem, try using all your standard tricks on it. Probably none will help. But perhaps eventually one will and you'll seem like a genius for thinking of applying that trick to that problem.
