Grew up on a ranch, so I had the luxury of carrying buckets of grain out to 50 steers twice a day throughout the winter, bucking hay bails in the summer, fixing fences, shoveling manure, harvesting wheat for 12 hours in a combine and driving tractor. Monotony was the real drag if you ask me, the work was fairly physically demanding just boring. Needless to say I always had a blast moving cattle with our horses and running our Bobcat skidsteer.
Spent 3 summers spraying weeds for the Forest Service, sometimes the weather would get up to 110 degrees, and I had to get up at 4:30 every morning. Bleh, again it was the monotony that drove me nuts, I liked it when I was given new challenges. I went out on a couple of wildfires and helped fight them, that was pretty neat.
I was a caregiver during college for adults with disabilities, most had some form of psychiatric illness which posed a real challenge (like trying to get adults with disorders such as bipolar disorder, oppositional defiant disorder or developmental delays to comply with the renal diet, etc...) I worked overnight shifts, although on a couple occasions they were more like 20-24 hour shifts. I had to do suicide watch on a couple occasions. I actually liked this work quite a bit and this was what drew me further into medicine. I learned a valuable lesson: treatment plans are only as good as their compliance.
Now I work as a rehab aide in a large hospital, and am exposed to all sorts of illness, I absolutely love the medical complexities of my work. I am the unofficial "expert" for using the lifts and mobilizing large patients in our dept, I've had to help with 400+ lb patients before. Despite all the precautions I take for my back, 8-10 PT treatments with highly patients that need maximal assistance can get pretty tiring. But I'm learning alot, and I've come to see the importance of early mobilization, especially in the ICU. Once again though, I'm ready to move into a bigger role as I am starting to feel pretty darned constrained within my current position.
I've found that the mentally challenging jobs have been my favorite as I tend to get bored easily, and in that way the "harder" jobs have often been my favorite. Hopefully I'll feel the same about medicine
