Everyone always tells me I'm an advanced rider and I am dumbfounded as to why! There is so much I don't know yet. I've only been riding 11 years. I've got my whole life to become an advanced rider. For now I consider myself knowledgeable but too young to have enough experience to become an advanced rider. All in good time. I'm in no rush to strap that label on myself.
I think a lot of it has to do with our family taking on remedial horses. A few with severe aggression and because I'm described by many as "All balls and no brains" I am the only one who is willing to work with a horse in that state. I keep telling people it's a lot more stubbornness than skill.
I think there is are different kinds of advanced horsemen. I know plenty of professionals who wouldn't come near some of my horses when we first got them with a 20 foot pole. Their expertise lies in something totally different.
