Well, then it would be interesting to know why these didn’t work.
Is it just a matter of bad timing, you couldn’t take a job in December?
Was there in fact no job on offer?
Did you apply and get turned down? If so, why?
The answer to these questions will help focus and narrow the next part of your job search.
The thing to remember is that being a pro is about primarily helping other people ride not riding yourself.
Your own riding gets put on the back burner. This is true for many instructors who need to make a choice between teaching a lesson for cash, putting a training ride on a client’s horse for cash, or working on their own personal horse (which no one is paying you to do).
It is also true when the instructor is getting paid day rates to take students to a low-level or schooling shows and handhold them all weekend, rather than take their own personal horse to a higher rated show. This is especially true for hunter/jumper around here at least, where the lower level shows top out at 3 foot 3. If you are running a robust kid’s lesson program and taking kids to the two foot nines regularly, you will have less chance to get to the 4 or 5 foots on your personal horse.
When you are a working student or an assistant trainer, you are on the pro side of the equation. What you want and need to do personally is always going to have to take a back seat to serving the paying customer. This is true for how you spend your time, and also how much time the main trainer is going to have to spend on you.
You might be in a barn with GP schoolmasters, but your day to day riding might be tuning up a Training Level horse for a client who can’t handle too many buttons.
Also most trainers are their own small business. They need a nest egg to get started and they need to pay themselves a salary out of the business after all expenses are paid. If you want to set up as a trainer, you will need to think how you will finance the startup costs, and whether you can make an income from the work.
Anyhow, I’m not sure what your ultimate goals are.
Do you want to work in the horse industry in any capacity possible, teaching beginner kids lessons at an hourly rate or just grooming at a show barn? Would you be happy if your riding stalled out at the current level but you could make an OK income teaching kids 5 hours a day and mucking stalls for 2?
Or do you really just want to improve your own riding and train your own horse with some help from a good coach?
If the latter, honestly I think getting a good paying job and then paying your way as an amateur rider would be more satisfying.
