Who is self employed?

I have been self-employed since I got out of school in 1973. I went to vo-tech for autobody repair and immediately opened my own shop. I rented various locations until I bought the building I'm in now in 1985. I stayed in the same little town all these years. For years I worked by myself or with one part time employee. I now have one part time employee and a nephew that is learning the trade. 2010 was probably the best year I've had in quite some time but I'd like to get out, I getting tired.
