I trained my first horse when I was 11. I had been taking weekly lessons for about 2 years, and my parents bought me a 3 year old unbroken ridgeling. I continued with the weekly lessons, but no actual training help. He taught me how to ride, and to train. Thankfully, he was honest and athletic, and didn't have a mean bone in his body. (Didn't mean he never acted up - I swear he would buck like crazy when he felt good, then when he felt me start to slip he would stop till I got my balance, then off he'd go again) ANyway, he was nationally ranked on both the hunter and jumper circuit several years later, and he was even shown in trail abd western pleasure a few times and did great (that was back in prehistoric times when it was possible to have a horse show both ways). Anyway, he ended up a GREAT horse - I could put a green kid on him and send him in the ring and he'd usually come in the ribbons. He even did somefairly advanced dressage and did well. About the only things he WOULDN'T do was let someone get on him that was 'going to show him who was boss" = they inevitably ended up oin the dirt . Now, 40 years later I am traiining my new horse and she is coming along beautifully so far. Still have a long way to go, but I'm on no hurry.
