I had a fear of getting near a horse and on a horse. I fell off my horse and it stepped on me.  when ever I could I would go sit on the other site of the fence and just getting comfortable being a round them again.  When I was comfortable with that I would sit in the pasture with them. When I got comfortable with that I would get on the horse. I finally got over my fear even though it took 2 years.  This is how I show Discipline.
