My answer (non-trad) ws that I kept getting drawn back into vet med. I made the decision to pursue another animal field, but every chance I had, I was still working with vets. There are a lot of other features for me; I like working with people and their animals. Teaching is something I enjoy. I also like puzzles, and some of medicine (especially with my interest in exotics) is puzzle solving. I like having conversations that most folks would rather avoid, so calling up the world expert on binturong's and spending time discussing what's wrong, blood work, etc is fun for me (use to volunteer to do that.) I also enjoy reading the latest research; put me in a library and I can spend hours perusing science journals, so I appreciate a profession where there will always be new procedures, drugs, techniques and methods, where learning is always expected. Finally, unlike human medicine, I feel vet med gives me more control over my fate. I can own a clinic or pursue a specialty. I don't have to do a residency if I don't want to. I can also chose a career path with this education that lets me work inside or out. I don't know of many areas in human med where I could ever work outdoors.
You will need to figure out your own reasons, but sometimes it helps to hear others. My suggestion is to sit down and write out what you find awesome about vet med. It doens't matter how absurd it sounds, just get it all written down. Then figure out how to articulate it.
