Having a strong work ethic, always willing to learn and a positive attitude will help make a good name for yourself. Other professionals are willing to help someone out if they feel like the person is making the most of their time.
You can also start as a groom/rider in a stable, if your riding skills are good you probably get to ride more tan grooming and maby do som shows, and then get a network for other stables or sponsors.. it is a long way to go but worth it if thats what
sorry to say but you have to have money or it will be very hard to make it big. not saying it's impossible, just quite challenging.
I believe they need to find a good sponsor or a horses owner! But it's not an easy thing!
sponsors are their main source for sure
