There are more options than that in the horse world and every one has pros and cons. Maybe find people who work those jobs and see if you can talk to them about it or even job shadow them for a day to see if you think it will be a good choice for you.
Hi Chase! There are two very different jobs, I think it depends on what you like to do. If you are a riding instructor you will spend more time outside with horses and students, as a barn manager you will have a lot of paperwork to do which is not something that everyone likes aha
