Josepha, I could never write this...maybe some years from now?
For now, I'm still floating often between understanding and not understanding, how all the work in interconnected. The connections are sometimes very hard for me to understand and to keep straight in my mind. The progressions, what to look for at one stage that tells you are ready for the next, what a movement should look like, how to tell if a horse is using him/herself in a good and healthy way, if there is enough energy asked, if there is enough relaxation, how the rider affects the horse (negatively and positively). Just because I am getting to a certain place with Tam, does not mean that I understand how I got there. There is SO much to know.
I see all of this information at times like a tangle of threads. Each thread is linked to another, or the threads can split and connect with two or more other threads and those threads connect to other threads...if it were all laid out correctly it would look something like a net...neat, tidy and it makes sense when you look at it. For now, I still have much of it a jumbled pile and I'm not sure mine is a nice net at all...there are holes in it that need repairing, etc.
I have a LONG way to go and may never have it clear in my mind. I envy your ability to simply lay that net out...all neat and tidy!
