OK, so the education, training, and day to day operations never overwhelm you. What about dealing with all the people, people who train you, supervise you, report to you, or you are assigned to train yourself, ever get overwhelemed by one or more of them ?
There is a lot to learn, especially for me. A lot to do. But it really is still less than working 3 jobs trying to make a living in either fire or EMS. Eventually you sort out a schedule and it becomes a pattern.
Myers-Briggs seems to reliably classify me into their ENFJ category. while I don't agree with all of it, it is fairly accurate. I am very adept with people, which I have noticed doesn't show up well on a forum, but does make working with people rather easy.
I actually like to learn, so even when I am pouring through research or endlessly reading textbooks, I find it sort of comforting in that I only have to concentrate on what I am doing at that moment. Focus reduces stress.
As for the people who train me, all except a handful are actually looking out for my best interests usually. The few who aren't are just neglectful, and I have more than enough to do to dwell on them. I don't have anyone who actually opposes me in my daily life. Maybe on this forum, but once i close the window they are gone. It also doesn't really affect me in any tangible way.
It is my day to day hospital responsibilities I actually enjoy the most. I love to see every patient, performing procedures, talking with them, everything about it, often times wishing there were more. Some specific things I don't really care for, but they are not overly stressful or overwhelming by a long shot.
As for my actual paying jobs, reviewing textbooks is not overly stressing, especially since I spend so much time with textbooks anyway.
When I am off from school, I teach. I sometimes find it hard to believe I actually get paid for it. It is hands down the easiest job I ever worked. Definately nothing even remotely overwhelming there.
Hard at times, for certain, overwhelming, not at all.
