I'm married and have four kids, though two have now left the nest. When I read this, I think about all the times I set aside my code to do something more important - interact with my kids, nurture my wife, and pursue hobbies outside the technology world (I run, bike and sail).
But ... you might be surprised to learn that I love that tee-shirt. I think there are many who are misguided enough to ignore balance in their lives completely (this shirt is not for them). For me, technology is my main hobby. I get paid for it at work (aren't I lucky), sometimes I get paid for it at home (I have a consultancy) but most of the time at home, I'm coding (or even building electronics) for fun. Other times, it's a project I'm playing with that I wouldn't otherwise get to do at work.
In any case, I'm not advocating living an unbalanced life. Nor am I describing a life of crunch-time (my home projects very rarely have deadlines). What I'm saying is that I truly love the time I spend on technology and identify with the shirt as a statement of that affection.
EDIT: It's a rainy Saturday morning here ... I got the lawn cut last night, my daughter is away playing viola at a concert and I'm kind of chilling with my wife and son. While we're siting in the living room watching the rain, I'm updating the Ansible scripts I use to keep my laptops, and workstations up-to-date [1].
I've got two hardware projects planned for next winter - I'm going to get my COSMAC ELF [2] running again (my first computer based on an RCA 1802) and I'm going to turn my old Sun E450 [3] into a TEC-based mini-fridge for my office (if anyone needs Sun E450 parts let me know).
