As another person who was once a pro and am now and amateur with a day job, I would say that your Pros and Cons are the ones typically seen through rosey colored glasses.
The Pros SOUND like they are fantastic - until you are actually on your feet all day everyday working around horses, some of which may bite or kick or bolt at turnout or run over you during turn-in or get aggressive in their stalls during feeding time - now that it’s your JOB to work with them, you can’t ask someone else to help you. Being “active” sounds fun until it’s 12:30 and you haven’t had time to eat anything other than 1/2 a granola bar and your coffee is now cold in the office. You have hours, but at the same time, horses are horses and you’re really done when the work is done. Also, be prepared to have your cell phone number given to all boarders and clients and answer their texts and special requests at all hours.
The Cons don’t sound THAT terrible - until you factor in that you probably won’t get any vacation or sick days, and a 45 minute commute will be BRUTAL at the end of the day when you just want to be home already and when you have to get up in the dark day after day. Getting injured is a very real possibility, and shouldn’t be brushed off with a “or whatever” sort of attitude (see above about bolting, kicking, biting horses). The other cons are the physical fatigue, the burn out, and the lack of career advancement.
Please don’t get me wrong. I know that this lifestyle DOES and CAN work for some people. But for most of those people, the love of the horse is really what drives them to go and stay in that career path, not their sense of ennui at their day jobs. I would try to either find another desk job that is more in line with what you want to do on a daily basis, and/or focus on the things that the job can provide for you.
The horse industry is brutal. It is not a walk in the park. That said, this has only been my personal experience, and I do treasure the time I spent as a pro and all of the things I learned there. I tried it out right after college with no other day-job / job experience at all. If you can still come back to your current path after a few years off, I would say give it a go knowing all of the things folks have told you here on the forum.
