career specifically? Nope, not at all. There's so much more to life to be enjoyed. Do most of my own training, as well as helping other folks out in that area, too. Wife's a wonderful teacher when it comes to riding, and I think we just got another horse that'll act nicely as a lesson horse.
Other than that, I have my regular job in the cattle business, and in the next few years will farm this place myself (1200 acres combined grass/crop land), probably keep my day job, and train some more horses for other people as well. So, specifically horse related 'career', no way, but they definitely fit into my overall picture.
