Be Open to the Possibilities.
Having a plan is great. But, it frequently means you miss what is actually happening in the moment that is a precursor to what you would need to accomplish the very task you were meaning to do in the first place.

For example: You're approaching a jump. Horse is bracing laterally on the turn and picking up speed (which means he braced vertically against the bit, too!) Yet, because you decided to jump, you continue. You may get over the ump, but... getting over that one jump isn't really the answer.

Getting over jumps well is the answer. Now, you don't always have to stop going over the jump, but certainly take time to remind horse how you'd like the approach to be afterward. If you don't take care of this, you are then telling horse that how that just went down is correct. After all, you didn't ever say so. What else are you telling horse is fine, when it's not now you would really like it?

Softness and willing response vs. bracing and malicious compliance. One keeps getting better, one keeps getting worse.

Tom Dorrance must have had great reasons for not being famous. He didn't approach any horse matter in a way that the average person wants to "get something done". And most people don't want to start where they need to start. So, I'm guessing he only worked with someone who was open to not knowing and was interested in finding out.

Now, I'm not going biblical on you, it's just that everyone knows this verse - Ask and it will be given to you, search and you will find, knock and the door is opened to you. Nowhere does it say - tell yourself and everyone how good you are and you will be.
Every day with horses is one heck of a learning experience. Every nuance, movement, non-movement, notice what you notice. You don't have to DO anything, but notice, be aware and wonder.
You will not get to be a horseman without constant learning. There really isn't a get to. It's a constantly changing awareness of what is. Then, you can do stuff and see what happens.
