Good on you. Sounds like you have a great new job. Change is very hard sometimes, but if we don't take the opportunities we sometimes regret what might have been. You are obviously regarded highly at your current barn, so your work ethic speaks for itself. New job, new experiences, new people/horses, More knowlegde !! As we say in Aus "Go For It"

Today at the age of 39 I decided for a career change !!. A new vet clinic is opening in our area, and i have applied to train as a vet nurse. Keep your fingers crossed xxxxx.
It is what I always wanted to do, but circumstances have prevented me. I am now in the position to fulfill my dream. (just have to get the job First).

Best of luck
