OP, don’t be so hard on yourself. You’re not perfect. You never will be. No one in this sport is.
A kindergartener could probably give me a lesson. I would tell him or her 5 phrases to repeat for an hour. They’re the same things I’ve been working on for years. They will probably be the same things I’ll be working on in the next 5 years. But… I’m better today than I was this time last year, and that counts for something.
I feel a lot of pressure to be a strong rider. I don’t need to be an Olympian, but I am the BM, and sometimes it’s hard to have students riding circles around me in lessons. But they’re better riders than I am. Period. I’m there to improve the best I can despite my limitations, which are numerous. I don’t have an athletic bone in my body, I have no coordination, I am fearful, I am anxious, I am out of shape, I don’t have time to put into the saddle, I don’t have access to full time training, etc., etc. So I just enjoy my saddle time and try to improve the best I can.
The most frustrating thing? I’m terribly inconsistent. I can go and lay down a near perfect course (for me), and then re-ride the same course and chip half the fences. Or last week, when I executed an exercise flawlessly, and then fell off at the end because I didn’t decide if I wanted to turn left or right. Really.
My advice? You and the clyde might not be a good fit. The pony may not be either. I feel best on horses between 14.2 and 15.3. They fit my legs and short upper body. I hang on better. I use my legs better. I ride better. Try to get on a variety and see what you like. But have fun with it, as other posters have said.
Also, little goals are good, but your goals shouldn’t be to be perfect. No one is perfect. Keep your hands the proper width apart while trotting. Keep your legs in the correct position during canter transitions. Even top riders shift their bodies (sometimes by accident) during a ride. Don’t reach for perfection if you’re an A type. You’ll always disappoint.
