I think reading a variety of texts, magazines, and books and watching videos and horse videos are helpful in developing understanding of how and why, but the key to great horsemanship is the ability to apply the lessons learned. Having the feel necessary to know when and where to apply pressure, and the moment to release is critical. Like Rob says, that hands on is critical, but I think the education behind it can be gained through a combination of lessons, text, and video... so thanks for offering another opportunity for learning
