When people ask me this same question, it is hard to explain what I do, or what my company does.
I work for a global supplier of "outsourcing" solutions to automtotive manufacturers and their dealerships. And even I am unsure of what this means.
Basically I am involved in consulting/training services to auto/truck manufacturers and their dealerships. I manage a group of consultants, manage projects contacted by auto companies, build software applications, and do some instructional desgin work. My office is in Michigan.
What this really means is that I spend most of my time on a computer in my office, at home in Palm Springs; while gazing at Mt San Jacinto. I do have periods of extensive travel, as I am a "subject matter expert" in running automotive dealerships and other businesses, at least that is what I am told I can do :)
Since I telecommute, I have a large degree of control over my time, and completing projects on time is the main focus; not whether I am "on the clock." This does allow me more control of my time and opportunities to engage in outdoor activities, than most peope who work full time. And I often am able to work in my mobile office (a tent trailer) in some remote location away from people. My wife and I camp together around 100 days a year in our ten trailer, and I also get in my fair share of backpacking too.
And so now everyone still probably cannot figure out what I do. That's okay, I can't either :)
