Are you pretty fresh out of college?
There will be dues paying in any profession. It might be helpful to read about people like Laura Kraut, Kent Farrington, Nick Hanness, etc., and what they did to get where they are in terms of riding anything and everything under the sun. Have you thought about being a working student for a trainer you really respect? Could you supplement the work you were doing at the second barn with clinics with top trainers, or bringing along your own horses on the side? Did you demonstrate that you could develop a horse up the divisions, and then do it on a variety of horses? That would surely get you noticed anywhere.
If you have a passion for horses, you do need to reflect on something as simple as what it would mean to be indoors all day…behind a computer…etc. There can be plusses and minuses but you have to ask yourself if you are constitutionally equipped to handle office life.
Office life is going to involve dues paying, as well, and depending on the profession, it may take years to earn the chance to have big time responsibility. Horses or otherwise, for a real career with staying power, there really isn’t going to be any way around the obligation to spend time in the trenches, hopefully learning from mentors you respect. There are very few overnight sensations in any industry. Have to work hard and hopefully find something where the day in and day out of the work itself is gratifying, even if it is not glamorous initially. It’ going to take patience and giving the positions a real chance.
I have had good professional success outside horses but it’s at the expense of getting to ride much or show at all due to the time commitment. I have lived the other life where it’s all horses, all the time, with no stability and walking a tightrope all the time. Maybe you can find a middle ground, like nursing, that gives you a reasonable schedule and reasonable income and lets you ride. Having lived both extremes, I vote for the professional success outside horses, and riding less than I would like, because the continual financial stress of trying to support horses with just horses can really eat at you. That said, I have to have animals and outdoors in my life as I would literally shrivel up and die inside if stuck in an urban apartment or office all the time.
I would encourage you to set goals that are based on incremental improvements and not just some eventual end goal of riding fame. If the process of gradual incremental improvements is not rewarding in and of itself, it might be time to think about a career switch to something where the necessary dues paying does not feel like drudgery or spinning your wheels–hopefully you find something where you enjoy putting the building blocks of a career together.
