Just laugh it off. Always remember that they are animals and they have off days just like us. You just have to keep positive and focus on the good in the ride. Also don't force anything of your having a bad ride don't force anything to happen. 😊
Maybes change of scenery would help, I mainly train dressage and my horse is an ex polo-cross horse so every now and then I try and take him on a long trail ride or do some cattle work with him of just have some fun
Something that helps me is realizing that I'll have bad days, and that's ok! I know that next time will be better, and I can learn from not doing well. That said it's always good to keep trying!
