I have a friend who has done what you want, but she has had years and years of experience first working for a large barn/breeding/training facility first. Go find a barn run by someone whose horse experience you respect, and volunteer to muck out stalls, groom horses, feed, be a go-fer -- do anything. When you are older, you will have a job waiting for you more than likely. From there, you learn, you learn, you learn. If when you are older and you are still wanting to do this, you will then have the experience and practical knowledge you need to run the business. Finish school, go to college and take business courses. Be a sponge around those who can help you realize your dream. You may not be rich, and it's a heck of a lot of work, but if you truly want this, you can do it.
