I was asked what I thought was the most important thing a person needed to do to make changes in their horses. I had to consider this for a moment. Then the answer was obvious.
If you can't commit to the time to work with your horse then improving your skills is still achievable through lessons on school horses, etc. However, learning better skills without making enough time with your horse will leave your horse’s education stagnant.
I sometimes explain to students that the simple difference between me as their teacher and them as the student is that I have spent a few more thousand hours working a few more thousand horses and making a few more thousand mistakes.
