I worked a couple of years in a company called BlackRock. There's a group there called PAG (Portfolio Analytics Group), made up of mostly fresh college graduates. In the beginning, the head of the program would feed us the Kool-Aid about how the long 16 hour days would be so worth it after a year or 2. Sure, we'd be half-awake when we came in at 6 AM, and half-dead when we got to leave at 10 PM.

The kicker was he told us while it'd be tempting to just go home and sleep after we left, we should instead head straight to the GYM and workout for 30 mins, then go to the bar for a few hours because it would keep our "sanity". Hah.. sure, you know what else would keep you sane? QUITTING and working elsewhere.
