when I was young. I wanted to ride bad.. real bad and every chance I got I rode. The first time I was thrown, it scared me to death. I had the urge but was scared. I finally told myself what scares me more, Riding and getting Hurt or Never Riding Again. Never Riding Again scared me more, the urge overcame my fears.
I looked at it from a functional standpoint. I rode bicycles, motorcycles I have had bad wrecks on both and it didnt stop me from riding them. Horse Riding is no different to me. I look at it as a form of transportation, but you can't bond with a bicycle or a motorcycle.
Take it slow. Don't set yourself up for failure.. Ride Confidence Builder Horses and stay in controlled environments until you are confident enough to venture out. Baby Steps and you will be fine.
