Well, it certainly can be argued that you are a more successful business person if you're not getting ripped off by your negotiation counterparts as you fight your wish to sleep.

There's a reason I don't do the "fly to X in the morning, have meeting, fly back" racket. I always have either a night train or a sleepover in a hotel, when I have to travel for workshops or hands-on work - making me get up at 4 o'clock in the morning means my employer loses at minimum half a day of productivity or more plus either night trains or hotel are cheaper than the productivity loss.
