Or you totally love doing what you do at work and, after spending a week at the beach, you can’t wait to go back because you’re so close to solving that interesting problem you’ve been working on for more than a month.
There is danger to that as well. Work can be an addiction. It is often solitary and removes you from focus on your actual self, friends, family, or community, in favor of "the work."
Yeah but work isn't all there is to life, at least for me. There are way more fulfilling things. If you like your work more than anything else in life, good for you. Different strokes for different folks.
