Kind of a newbie here as well. I have ridden horses and done some pony club and on and off lessons for over 30 years. Over the past five or so years I thought I was learning dressage until I started with my current coach a few months ago. Apparently, I have over 30 years of terrible habits to fix but I am now starting for feel like I am really learning something and becoming a much better rider.
In a few short months, I am amazed at how technical dressage is (and I love it!) and at how well my Arab gelding responds. I always thought the talent and training of the horse was the limiting factor in riding dressage, but I have humbly learned my horse can do anything I ask (lower levels of course) provided I ride him correctly and give the right cues. Hopefully next spring I will be brave enough to try a few training shows and then we will go from there.
