Ok - so I started breaking horses at age 13.
By the time I was 17 I had started about half a dozen horses under saddle...
I also had had my skull fractured twice
more than 6 broken ribs
four broken fingers
four broken toes
As I continued to start horses and work with problem horses in college, I worked for some medium sized breeding farms and gained a lot of experience. I also gained....
two more fractures to my skull
a broken arm
a hairline facture of my hip
more broken ribs, fingers, and toes
permanent scars on both hands from rope burns
I gave up training horses in my 20s when I became a mother. I was simply going to pay someone else to do my training for me... but could never find soemone who actually knew more about horses than I did. So I trained for myself, just not others.
At 35, while starting a horse for my daughter, I got bucked off and crushed my spine. Now, at 42, I can't work at all, I live on so many pain killers that I can no longer drive. Hopefuly this summer I will have full reconstructive surgery which although it will keep me from riding for at least a year, might bring me back to functional.
So I ask you this - is it worth it? Honestly, if you are good enough, train your own, but don't take on someone else's problem. It is not worth it. The pay sucks and it is not worth your health.
I quit one job when the owner of the stallion I was riding didn't like that I was having trouble with a trot canter transition. The stallion had not been ridden in over four years and was really rusty. So the owner chased the horse with whip WITH ME STILL ON THE HORSE BAREBACK... that's where I got my broken arm.
Here is the mare who broke my back at an event two weeks before the accident. We are the middle horse and rider.
