This question comes up an awful lot. Not just with horse riding, but with acting, singing, dancing, running, gymnastics. I have felt like that in the past, and it is a horrible feeling. I felt like this both with acting and horse riding. But, the thing is. No matter what activity or passion it is, if you love it that much, there shouldnt be an age limit on what you love. And, horses really couldn't care less about the age you are, so why should you? All horses care about, is its owner. Whether your a 15 year old horse owner, or whether your a 67 year old horse owner. Horses want love and attention from YOU. It's hard to shake off the fact that maybe you are 47 and you have just started lessons. I don't know about you, but at my old stable, there were girls just aged 7 years old! It's surprising. But, in my opinion, children don't take in things as well as adults do. My first time on a pony was when I was about 6, and when I starting riding horses when I was 12, I couldn't remember squat about what to do. And even 12 is rather young to be doing such a dangerous, committed sport. I'm 15 now, and just about to go to a new riding school. Many people would complain that I am still too young to be doing it which puts me in a vulnerable state against such a huge, robust animal. But I say, hey? I love what i'm doing. I wouldn't change it for the world. No matter what age you are, you can achieve anything if you put your mind to it. Hope this helped to anyone struggling with the whole age thing. Just enjoy what your doing!
