Well actually I am a trainer.... :) so for the most part I'm on my own. But we get a grand prix trainer in from Colorado every couple of months to work with all three trainers at our barn. She's absolutely incredible! And she does clinics with George Morris, Geoff Teal, etc. So I guess no matter how good you are you could always learn more. We also have an incredible dressage trainer come in every other week who's a silver/bronze USDF medalist and I take a lesson or two from her every once in a while. Other then that it's just me and the 2 other trainers at our barn watching and helping each other out.
Did that come across as cocky? Sorry if it did! I was just trying to share my position in the matter. That and the fact that even those in teaching positions always have a lot to learn from someone else. Why be cocky about what you know? There's always more to learn and always someone better then you!
