I feel compelled to discourage defining absolutes...for example: "I will never work past 5PM".

As I said earlier, I encourage and model balance. But I also model "rising to the challenge". In other words, I can't predict tomorrow, but I know that if something urgent arises, we all need to hunker down and get it done.

Today, I did an 18 hour day, but yesterday I left a few minutes early to capitalize on the great weather for a 20 mile ride. 19 miles into that ride, I stopped and talked to my boss/CEO while he and his wife walked their dogs as they were capitalizing on the good weather as well

But, if everyday is a crisis requiring everyone to always hunker down...THEN that's my job as boss to reconsider staffing and resources to reestablish balance.
