Hi Brittany! :) I'm Shelby, I'm 14 and just got my own horse for my birthday two months ago. I've been riding since I was 4, and it's a LOT of work. I ride English mostly, with barebacking too. As far as tips and advice? Just keep working on it. If the barn you ride at is okay with it (like mine is), offer to help with chores (feeding, mucking stalls, cleaning tack, etc.). My 'philosophy' I guess, was to do anything I could to be around horses. This will make you feel more comfortable around the horses at your barn, and the barn owner/manager will feel more comfortable around you! The more people around the barn trust you, the more involved they'll let you be with riding. Don't get discouraged, it will take a bit to build up the experience you need to excell at riding.
I just sounded like a nerd. ^_^
Anyway, probably should wrap this up so I'm not lecturing, but, in short, congrats on joining the riding community, and good luck with future lessons!
