I always liked her, nice people. Wonderful Hunter rider.
Please note she has primarily ridden other people’s horses and been paid for it because she is dam good at it. She stepped back from her own personal goals for some time to teach and train for the family business. Then went to work riding for somebody else to pursue her own goals. The horses she has in training now are largely funded by others.
Think Kent Farrington is a better example of starting with nothing. Middle class family with NO horse background. Started with weekly up down lessons, working student type. He has said one of his biggest challenges is finding the right horses, owners to fund them and hanging on to them. One of his current owners has been with him for a very long time.
You could put Mike Matz in that starting from nothing group but he took another path and married well. Very well and into a top horsey family.
