Good question
I was on track to be a Surgical Tech, but we then bought a house 3 hours away from the closest school site. My husband was a Lead Medic in Alaska (Chena-Goldstream, if anyone knows the area) for 4 years, and we connected through the medical knowledge yearning parts of our personality (that's a really long way of saying "we both wanted to do more with our lives in the medical field")
I think the "want to help" part is just that - I want to be able to help those I can. I've spent years around Fire and Rescue crews, and most of the locals here are friends and neighbors. They are good people, hard working, fair, and I can only hope to keep up with them.
A big part of this is personal greed... I want to be able to help those who can not help themselves (part of being a mom to special needs kids, I'm sure). I have even thought, seriously, of going on for the Pediatrics speciality courses. No, it's not to have a chance to save someone, and yes, I know that the chances are slim of having a "happy pediatric" call, but there are not many around here who can handle pediatric calls. Can I? I don't know. I have seen many things in the OR that were bad. I know things will be worse as an EMT.
All I can do is everything possible to help whoever needs help.
I don't know if I am likely EMT material. I know I'm not perfect But I do know that I have spent 3 years deciding this, and I hope that I'm ready.
