>Do you ever find yourself interacting with a carpenter and asking him why he doesn't build additions to his house, or his friend's homes in his free time?
What about an accountant? Ever quiz them or deride them for not going out of their way to balance budgets and crunch numbers for family & friends?
These make no sense. There's a huge, huge difference between building an addition to your house and building additions on all your friends' houses. I like to do all the maintenance on my own car, and I'll do it on my spouse's car, but I'm not about to volunteer to do maintenance on all my friends' cars too unless they're having a real hardship and need a little help to get out of a bind. I may know how to work on cars, but that doesn't mean I have infinite time to help everyone I know with theirs; there's other stuff I'd like to do with my spare time. If a carpenter has no interest in doing any carpenter-ing on his own personal house, that doesn't sound like a top-notch carpenter to me. I knew a guy not too long ago who was a carpenter/woodworker, and he absolutely did have a bunch of stuff in his house that he had made himself.
For an accountant, I would really hope that a decent accountant would want to do a great job balancing their own personal household budget for their family. If you're an accountant but you can't manage your own family's finances, then I wouldn't want to hire you. But that again doesn't mean you have infinite time to balance budgets for all your friends and extended family.
If a guy is a plumber but then calls another plumber when he has a leaky pipe, instead of just fixing it himself, what does that say about his professional abilities? If someone is an auto mechanic but doesn't even do his own auto maintenance and repair, what does that say about his abilities?
If someone is a professional and passionate about their career and work, then I absolutely do expect them to carry that into their off-hours to some extent. I would not expect them, however, to spend all their free time doing free work for all the people in their life. But I absolutely do expect them to make use of their skills for themselves and their own household. I'll make an exception for dentists, however (just for themselves).
