Congrats on the new horse. Instead of buying another horse, use some of that money for riding lessons. An experienced trainer will put you on the road to success. If you want to run barrels or poles, there is more to it than just running the pattern. Basic horsemanship skills come first.
If you don't know how to ride, you can make major mistakes without realizing it and ruin your horse.
Don't expect your horse to teach you. It can't. The horse will only do what you tell it to do.
Good luck with her.
PS. I hope that you bought her with a recent negative Coggins Test. Even though it is too late, a veterinary pre-purchase exam can save a lot of heart ache later.
