HELP THE CLIENTS! That is # 1 with my guiding jobs I always had great reviews for the clients cause I use to help them ride, tell them how to sit, and lean going up and down hills.. or stand up and lean forward when the geldings had to pee.. LOL don't worry about you seat, have a loss rein and a kind hand for the horses.... They will notice your confidence.. And be open to taking advice, everyone does things different, if you try it there way they will notice your flexible. CONGRATS! This kind of job was one of my best summers ever!
