The first time you ride a horse, hopefully, you won't fall off. Hopefully, you were given a nice, calm older horse. But one day, if you graduate from said older horse and ride something younger you will fall off. This is a fact. Perhaps it won't be serious; a bruise, you'll be a little shaken up, you'll get back on and be fine. Perhaps, you're first time you'll get a sprain. A broken bone. Need plaster. But hopefully, you'll get back on. The first time I fell off a horse, it shied at a plastic bag and attempted to gallop sideways. It wasn't until he realized how impossible that is that he tried to turn, and I tipped over his shoulder. In the world of horses, they say it takes seven falls to make a rider. I'm not so sure. Really, the best rider would never fall off. They would stay with the horse, move with it and balance their weight depending on a buck, or a rear, or a shy.
The first time a horse bucks, you should learn they way its body moves and, though you fall off that time, you stay on the next time. If you are a good rider.
The first time the horse rears, you may not grab its mane fast enough, so you would fall off. But the next time, you would have learnt, and you will stay on.
The first time the horse shies, you would feel its body bend to the side and gasp at the speed with which your horse whips around and runs away. But the next time, you would not fall off.
The next time, you would never tip over the shoulder because of a faulty canter. You won't roll off at a refused jump. You won't collapse into the midst of a dozen racing horses. Because you will learn.
But you don't learn. That's a fact. If you fall off once, you will fall off again. And when you fall off, don't check for mundane things like whether your legs are still bent the right way or if your skull is in one piece. You should be thinking two things: "Catch horse. Get back on horse." Every time you get off, you must get back on. The only exception to the rule is if someone runs up to you with a white face screaming at the people behind them "Call an ambulance!!" You don't consider not getting back on. If you've fallen once, you'll fall again. But if you've never fallen, you're one lucky bastard, or you should get off the merry-go-round.
