Go and have a Fun ride forget the progressing, get out of your head. Best wishes
Set goals. First one for everyone you ride. Then a weekly goal, a goal for the month, a goal for the year, and a goal for your riding career.
I do the same as amber, I also make sure to set goals, and pick out the little things not only about my horse but my own equitation that I'd like to fix.
I read a lot and watch YouTube videos, some of which can be very helpful when I ride. By watching other professional riders and looking up different exercises to do you can find ways to progress with your riding, not only for you but for your horse as well.
