I totally agree that a long work week is not a badge of honor and that the results of your work should speak for themselves. Things take time and sometimes you can't rush things.
I've worked crazy long weeks and its not glamorous and, in my opinion, just straight unhealthy on so many levels.
I think the challenge in working 45+ hours/week is maintaining adequate sleep/diet/exercise/social so that you can remain productive and happy over the long-term. Best of luck.
