Regarding professions/jobs...
I work so I can enjoy my time off. Work does not define me, nor does it need to fulfill me, it's work.
I was pre-vet in large animal (we never used poo for lube and did change gloves between cows), but life happened and I had to go back to a full time job. I was upset for the longest that I didn't get to finish.
Now? I work half the year and make as much or more than I would with DVM after my name, all based upon experience outside of college. I'm good at my job, but I don't love my job. The best part is I don't have to worry about my job when I'm on my off time and can do what I like without worry of being called in.
Dude, I wish I could have read this post back in 2000 when I decided to change careers and pursue my dream (which turned nightmare, lol) of becoming a vet. Everything you said is so true, real, and sensible.
I let the letters after my name define me, and it set me up for many years of beating myself up, especially after I left the profession. You are absolutely right: WORK DOES NOT DEFINE YOU. It's taken me over 50 years of living and learning and therapy and self-work, losing loved ones, losing my marbles once or twice, to learn this. That is a long time.
I wish you, or other people, had told me this. A big reason for me becoming a vet was living up to my (unrealistic) expectations, and trying to impress my family and others.
I love my free time now, I work as little as I have to in order to pay the bills, and yes, although my work does fulfill me--it is a job. It does not define me any more. My chickens and my dogs don't care if I have a DVM after my name that I'm not using so much these days. My husband doesn't care what I do for a living, as long as I'm happy and sane.
Bottom line? You gotta do what makes you happy and sane. Being a vet does not allow you much (if any) free time. That said, I'm sure there are plenty of vets out there who love their life, and I applaud them. It's just not for me, who likes to spend many hours farting around on the computer, in my coop, doing yoga, and getting a solid 8+ hours of sleep a night.
To each his own, right? Free time, mental health, and good sleep, IMO however, are highly underrated.
