Oh, and I suggest anytime you go on vacation to never take a laptop with you. Even when I would just go to conventions for that entire time I would never check email etc. It really works wonders for your psyche.
You'll also soon realize that what you think is important, it's really not that important. The world didn't disappear just because you didn't log on.
And on Holidays I havea 24-48 hour hiatus. Like on Christmas Eve I'll stop working around 4 or 5pm, and I will not go back online until the 25th around 9 a.m.
