you look like a naturally talented rider", that's a direct quote from YOU.
For a rank beginner who doesn't understand the concepts of following the horses movements, can't show an independent use of your hands/legs/seat, and has no concept of how to influence the horse with your body.. sure... you're great. You're great for a beginner. But that's what you are: A rank beginner. An "I've been riding for eight months", absolute beginner, beginner who is still learning how dangerous and difficult riding can be.
Can you honestly tell when a rider's weight is preventing the horse from cantering or turning? Can you distinguish between the pony that appears naughty because he doesn't want to, from the pony that can't because the rider is interfering? Can you explain to the kid why the pony won't do it, and how to fix it? Or are you just telling them to set the head and smack the pony to go? A good trainer should be able to teach the "why's" and "how's" for everything. You should be able to explain exactly what muscles are used in posting the trot, why we use those, and describe in different ways what the correct feeling should feel like. How can you do that when you don't know what it should feel like? How can you teach someone, who knows nothing of the correct feel, how to feel when they are following the motion of the horse? You weren't following the motion of your horse in the video, how can you teach others how when you don't know?
You've been riding for 8 whole months. That is still rank beginner. We've all felt like big know-it-alls who could handle anything at that stage. A year, or two, later you'll look back and wonder how the heck no one got hurt worse than they did (which hopefully they won't).
I get that you feel you're more then ready to do this... but horses have a horrible way of teaching us humility when we get in above our skill level.
I've been training for teaching under my trainers and they have no hesitations about putting me in this position.
What you'll be teaching these kids is that it only takes 8 months to learn everything they need, and then they can be a trainer too! Which is exactly what your trainer has taught you.
Let me put it this way... Let's say you'd never driven a car before and you paid a driving instructor to teach you. That driving instructor teaches you that you should keep one foot on the brake and one on the gas at all times. Because you've never driven before, you accept his teaching as 'correct' because you are paying him to teach you correctly. But that doesn't mean what he's telling you is correct. In fact, if you went to any other driving instructors they would laugh at you. The problem is... you'll never know that your driving instructor taught you wrong because you don't have any other point of reference to compare it against. You assume that because they are a trainer, that they know what they're talking about. And they SHOULD
know what they're talking about. But the fact of the matter is, there are thousands of amazingly crappy trainers out there churning out riders who even more poorly trained.
This is the situation you are in right now. Your trainer is the driving instructor... and soon you will be the driving instructor. And both of you are creating little driving instructors who don't know any better.
By the way, how dare you insinuate that I am going to get someone seriously hurt. I will not stand for this blatant disrespect! I do respect the knowledge you have presented to me, but the video you see is on me riding dressage, not my teaching abilities. You have no idea what I am able to do in that area, so do NOT say that I am going to get someone hurt based on nothing at all besides the fact I have been riding for almost 8 months.
Dressage isn't the issue.
I'm not saying you will willingly, or knowingly, put someone in a dangerous situation. It's your inexperience that will cause you to put yourself and others into dangerous situations.
I'll leave you to your own choices... I wish you'd take some lessons from other trainers for a while, experience different trainers, take the next year to learn how to rider better before teaching others. I'm pretty sure you're not going to do that because you've already made up your mind that you're qualified enough to do this... And you want the free pony.
