Um. That riding instructor doesn't represent all riding instructors.
That person sounds pathetic. Ditch that one and find a REAL riding instructor.
You can learn to ride on your own, BUT only if you also read books and watch dvds ...to find out how to ride CORRECTLY...yet that will only take you so far.
It's not about sitting on the horse, pulling on the reins and kicking.
It's about balance, learning how to use your seat, legs and hands correctly to not cause the horse any discomfort and to learn to work together with him.
You got 2 lessons from an idiot. That doesn't add up to anything. Find a real instructor who has real lesson horses that can teach you how to ride.
When you have someone WATCHING you....able to tell you when your seat position is wrong, when you're not holding the reins correctly, when you are using too much leg or not sitting up straight or.... that helps A LOT.
People who really want to learn to ride take lessons for a reason. Yes, it's easier to have someone there coaching you in what you're doing right, and wrong....
Also...it's not just about riding....it's also about learning horsemanship.....what does it mean to be a horse....the prey instinct in the horse....how horses react properly and why they act with unwanted behavior.
The horse that you rode clearly wasn't a good lesson horse because he didn't have patience to deal with you. He was basically telling you that you don't know what you're doing, so he can't listen to you....and he'll try to fight the rein pressure and go where he feels safe...to the barn, to his buddies. This is exactly what can happen when you don't take lessons and just go buy your own horse and don't know what you're doing..... Some horses will be forgiving and easy going, some won't.
Lease a horse and take lessons from a real instructor.
Intermediate riders have an independent seat. They are more confident when things don't go just perfect, they know what to do, because they understand the horse better and because they know how to use their seat, legs and hands correctly and not cause problems to escalate.
Advanced riders can ride anything from a horse that's never been ridden before (unbroke) to a horse in a certain discipline...with confidence. They may compete in higher level stuff.
A basic rider just knows how to be balanced and maneuver with the reins, but if trouble starts (the horse wants to go back to the gate or to the barn), the basic rider might panic or fight the horse and cause more problems....a basic rider can ride a well broke horse that's forgiving, but may have a lot of trouble riding the horse that isn't so broke. It's really a beginner rider. not a basic rider.
