However, I think it's important to remember that we can just as easily get caught in the trap of being present with our family, but not "present", because we're stuck in a 9-5 job that is sucking the soul out of us.
I'm currently in a position that consists about 80% meetings and 20% reading/responding to email, when I would so much rather be coding. I come home feeling unfulfilled, and am irritated way too easily.
Some people can still cope with a job like this and separate themselves from it as to not affect their home life. I wish I was one of those, but I'm not. And since I recognize that I'm not, I have chosen to find -- and have found -- another job that without a doubt will not have this impact on me.
If you're in the same boat, and are not able to cope and separate yourself from the drudgery of your 9-5 job, find one that you enjoy better. And I personally think it's worth even taking a cut in pay, if you can and if you have to.
