when you are out driving around, maybe on the weekend with the wife and you go by houses that you did work in, and remember the job and the things you did? I live in what they call a tri city area which is pretty big but over the years I have worked all over the state and into Maine, Mass, and VT as well. I don't consider myself to be particularly old but I have been plumbing for about 36 years now so it occurred to me the other day that there are a crap load of houses and businesses I have done work in or for over the years.
I think for me that that is one of the reasons I love my trade so much, because I remember a lot of those jobs and it's nice to know that you have left some small bit of yourself and your skills and talents in so many places. Sure has sitting in some cubicle selling time shares seem like a really crappy job.
