If you want to eventually become CEO of Goldman Sachs, then you need to put in the hours and show how dedicated you are.
And here's an anecdote about current Goldman CEO Lloyd Blankfein, which appeared in Thursday's New York Times DealBook column:
'At one point in his career, Mr. Blanfkein traded the Japanese yen and while out of the office got currency trades on his pager.
In those days, before he had a driver, he typically took the Seventh Avenue subway line home and often waited for the train at the top of the subway stairs rather than stand on the underground platform where his pager would not work.
When the train came, he would make a run for it, ensuring he had the latest quotes before heading underground'.
And our Lloyd's been running ever since.
