Once, about 10 years ago, I asked God for patience. I'll never forget this. I went to work for a grade school, helping a child that has behavioral problems. I'm back to working with horses.
The horses are tied in the barn for a short time to help with patience. Learn to stand still. Learn to stand still when your buddy leaves. Learn to stand still when you are alone. Learn to stand still when other horses come into the barn or leave.
