Do you consider yourself to be, or to have been, an expert in any field? Although I am posting this in the jobs category, it doesn't necessarily have to be a paid job, and, since we're seniors here, we may not have kept up on things sufficiently to be considered an expert today. Also, do you think that others would have considered you to have been an expert in that field? For example, I can consider myself to have been an expert in the field of Emergency Medical Services because I have worked in pretty much every aspect of EMS, and taught it. In fact, I taught the instructor courses. I have reason to believe that others would have considered me to have been an expert because I was in demand, and because eight different courts accepted me as such when I was called to testify as an expert witness in malpractice suits. However, I have never considered myself to have been the best there ever was in the field; I've had students who became better paramedics than I ever was, and I no longer consider myself to be an expert because I haven't worked in EMS for more than twenty years and there's a whole lot of new stuff that I haven't kept up with, and I've probably forgotten some of the old stuff. On the other hand, while I was paid very well as a machine adjuster in a career that spanned three different paper bag companies, I do not consider myself to have been an expert on paper bag machines. My mechanical aptitude is not particularly high, and it wasn't at all uncommon for me to face mechanical problems with these machines that I couldn't figure out. I did well as a machine adjuster because I took it upon myself to see to it that the machines didn't break down, to begin with, by keeping them clean and lubricated, and by paying close attention to the little noises that might signal an impending problem, fixing it before it became a problem that I couldn't figure out. Most adjusters left that stuff to the machine operators.
