I'm much like you. Rode a lot (read no less than three hours a day) in my teens and into my twenties. Then dropped out of the horse world. Work, kids, dating, college, work, travel, travel, travel, travel...marriage. I stopped traveling, sold the trailer, moved to PA with my new husband, and started riding again. My old self was almost fearless on a horse. Get on, go. Fall off, break arm? Pfft....get on again and ride until the pain is too great. Then ride in a cast. This new rider me is cautious and very aware of how much hurt can come of horses. I'm less excited by speed and behavioral challenges and more interested in horsemanship. I'm moving from barrel racing to western dressage and endurance, although I'm so familiar and comfortable with building a barrel horse, it might always play a role in my life.
Right now, I'm just looking for a new lease. I may have found one, but her ground manners are atrocious.
