I totally understand wanting to make horses a career. BUT as someone who makes her living with horses, I'd strongly suggest a backup plan. I have Mgmt & Finance degrees as well as investment rep (stock broker) licenses to fall back on should I ever need it. I worked for several years at a wall street based firm and trained horses part time. After my daughter came along I gladly left the corporate grind and went to horses full time to allow me to be a stay at home mom. Best decision ever. The money, not even comparable but I make more than enough to cover overhead on a pretty nice farm and a little extra in my pocket. Doesn't hurt that my hubby has a good job as well and he funds our retirement, vacations & mad money :) I could get by fine on my own without his income but I would be making do with a lot less. There are still some days that I think it would sure be nice to have those big paychecks again but then I remember that I'd have to wear a suit everyday, so I gladly pull on my boots and get to work
Just do your research and decide what you can & can't live without. Being on your own doing the horse thing, you will more than likely be giving up quite a bit until you get established. It's all about what sacrifices you are willing to accept to follow your dream.
