Don't spend all of your time in the saddle and spend time with your horse on the ground and doing tricks with your horse
Just try to get lots of research at home and don't be afraid to ask for help
My advice is safety first. Horses are dangerous animals. Get a helmet. Get boots. Boots that will withstand getting stepped on by a shod horse. Nothing hurts worse than getting your foot caught beneath a horses full weight wearing shoes. The boots should have appropriate heels to prevent your foot slipping through the stirrups. God I could go on and on. Make sure the horse can be handled by another person before you get near it. If you've never been around a horse it's best to watch someone else interact with one to give you an idea of what to do. Let me know if you have anymore advice!
