I'm an advanced beginner/early intermediate rider. I only ride western and lately I've been really starting to think that I'd like to get more serious about lessons and possibly showing. Right now I have the most amazing horse (my first horse) - 12yo BOMBPROOF mare that has been such a confidence builder for me. She is the sweetest, most gentle horse that anyone can ride; really as good as a horse can get. She is 14h and grade, though. I feel like this might be the right time for me to step up to something a little younger, bigger, and flashier :^) if I want to start showing. I'm already feeling so guilty for even thinking about selling Libby, though! She's been so good to me and my fears are that I sell her and they don't treat her right (I know I can do home visits, check references, etc., but it still makes me nervous), and I'm also afraid to sell such a solid, babysitter type horse and end up getting something I can't handle, and regret like crazy for letting her go. I can't afford two horses, though, and I realize that I won't grow as a rider if I don't challenge myself, but these are my fears...and I know I'll probably cry if/when I see her go! Any advice? How did you know when it was the right time to move on?
