Delta,
That was quite stupid...sorry.
What I wanted to say is that working 80 hours a week is not insane as long as you like it.
I'm among these people that are lucky enough to have full 24 hour exiting days.
Work, fun, necessities...it doesn't make any difference how much time I spend in one of them.
As long as the business I'm running and paid for is healthy.
I also wanted to say: keep spare time for fun.
Could be great diners, time with your kids if any, time with family, s$x with your GF/Wife, beers or wine with friends...
Cheers
Stephane
