I don't think any major life decision should be easy...and if it really is easy you may not have thought about it enough to recognize the negatives and how those will impact you (since the ideal is a job where even the negatives just aren't that bad in your perspective.) I believe that about relationships, moves, careers, etc.
I am a career-changer. I loved my past careers (2) and even my current side career. However, all my careers did was push me towards vet med. I didn't want to go to school for 4 more years, make less income, etc. I worked in a zoo as a curator. I loved showing up and taking a morning walk on the grounds, talking to donors, animal care, managing our interns, volunteers, and staff, making environmental and animal decisions, dealing with species management, hosting events. I often worked 50-80 hours a week, and loved it. I crashed in my office some nights, and often a peacock would visit my office window to wake me in the morning. Who could ask for more (except better income)? What I noticed, though, is that given the option of all my jobs, what I enjoyed most was working with our vet, whether it was dentals, surgery, blood tests, breeding, or trauma. Every spare moment was spent directly with our vet. I was at a juncture where I had the rest of my position running smoothly and was spending half my time working with our vet.
Then Katrina/Rita destroyed my job and my home...and I took a job with NOAA as an observer. I was paid well, but worked really hard. I loved the necropsy rooms, tissue sampling, examining the data, and figuring out what was wrong. Did we catch a porpoise (commercial fisheries) because of our gear, our location, or was the animal sick, and if so, how/why? I probably talked to our vets more than any other observer. I'd call to see if I could come in on my land days and my days off. I'd call to check on tissue samples and full necropsies. While I worked there, I loved ever minute of it. High adventures, lots of drama, dealing with difficult characters and seeing some magnificent vistas, and having oppurtunities that are pretty rare (not many folks participate in fresh marine mammal necropsies.)
So, a decade after graduating, I gave up the battle. I relocated with my husband, finished up pre-reqs (they changed a bit since I graduated), and applied to a couple of schools. I knew I would only apply once; I gave it all I could, and there really wasn't much I could do to improve my application. I was accepted at my IS school, relocated 3.5 hours from my husband (and have since dealt with a lay off, some illnesses in the family, and other hardships) restarted my side business of pet training (which I have done just about everywhere I have lived) and am now in the second semester of my second year.
The best thing you can do for yourself is get experience in vet med. Really think about the worst aspects of the job (and check out a variety of fields within vet med) and the issues in the job, and figure out if those fit into your vision of your future. If they do, pursue it full steam. If not, examine other career options. I thought I could avoid the trade off I didn't want by pursueing other fields, but it didn't work for me...so I came back. And while there were advantages to the traditional path, I like where I am now, as a non-trad. there are some advantages to this path as well.
