the greatest energy trader of all time on what being the best actually costs you:
"i would sit there from six in the morning to 6 at night staring at the screen. go out with people from the industry that night. dream about the industry. in the shower in the morning i'd be thinking about it. after doing that for 17 years, at some point i just had to step back."
nobody tells you this part. the people who become the best in the world at one thing are almost never the best at anything else while they're doing it.
