And I wouldn't play one on TV.
There are a few people in my life who have ailments for which I have no empathy. The first one restricts her activities, makes others suffer hotter temperatures than comfortable, and constantly talks about her pain. Another person is much less talkative about her problem, but it still dominates the conversation around meals. Both of the people have been to doctors, had tests run, and seen specialists. Neither has a diagnosable condition.
Most days I believe they have some discomfort. Other days I am much less charitable. The words that want to be released are "shut up" and "bear it." That is what I do, and I have a diagnosed condition that has caused me to restrict my own activities.
Having recently talked with one of the persons mentioned above, I decided that I would not have made a good doctor or nurse. My husband, ever the blunt one with me, agreed. "You have no empathy." (That's going a little far. I have some. A little. OK, not much.)
I certainly have the brain power to assimilate all of the knowledge required to be the doctor, but my personality would have prevented me from being a caring doctor.
Is there a profession that you know you could not have done? Let's not go the easy route choosing trash collector. Face it. If you had to be a trash collector, you could do it. Which profession would your personality prevent you from executing properly?
