An absolute great read.
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!
These “hits”, these flashes of insight, pay attention to them because they can illuminate a bigger picture and be the beacons on your way to genius.
