Welcome, & it's always nice to see a guy interested in horses!
True horsemanship is a grand passion, not just a hobby, nor recreation. True horsemanship takes an inner revolution in the human, & only a small change in the horse. It also takes a lot of time.
I recommend reading some of the masters' words, like the Dorrance brothers' (Tom & Bill). They learned horsemanship at turn-of-century OR & CA ranches, & tried to pass the knowledge on. "True Horsemanship Through Feel", by Bill (co-written by student L Desmond) would give you a fine understanding of what it takes.
