Obviously those guys are blessed with a certain amount of genetics, but they also spend more time honing their craft than anyone else is willing too, thats what takes them from the level of an every day player, to a god, who will go down in all the history books.
I have yet to meet a trader who was obsessed with trading, who spent every waking moment trying to be a trader, and trying to hone their craft, who eventually faileed, the reason why is because people who put that much time into their craft, who dedicate that much of themselves to a single goal, will never quit until they die trying.
Over the years, at prop firms, i have met alot of guys who thought they could walk in at the opening bell and walk out at the closing bell and be successful, and inevitably they all failed. Ive met a couple people who were mildly successful being there from open till close with no afterthought as to what the market is doing when it closes, but i have never met a highly successful trader who didnt spend exponentially more time in front of a computer than all the people who failed before him.
