The first time I was on a horse was a beach ride and ended up cantering. I was 12. Then I got private lessons every 2 weeks for 4 years and worked in a trekking yard every day riding 1-3 hrs s day in summer. I've also had occasional jumping and group lessons in between my private lessons. I've done a dozen or so hacks outside of work and ride less than sensible horses at work. Been bucked reared and bolted with. Worst ever was when a 16 hand refused a jump and i was hanging off the side.
Actually there was one time when I was riding one of the work horses and he was lazy and i only managed to get him to canter a few strides then the employer lady swapped me over with another work girl to see if she could do anything better and he bucked her off in 3 seconds in the first canter step - so maybe I am just VERY lucky..
