I want to do everything the correct way with my new girl, ☬❣ Zaynah Numair. What is the best way to train her? I already have her on the barn manager. What more should I be doing to make her the best I can make her? I don't want to screw this up like I do everything else. :)

All you need to do is keep training her in All Disciplines, and make sure not to enter her in specialty clinics or trail rides. Track training from week 4 to around week 17-20 (there are plenty of guides if you don't understand tracking training) Otherwise, you're good!
