How does someone learn to Joyfully endure trials?
I was in the US Army. I hated running long distance. I saw myself as more of a sprinter. I hated doing a timed two mile run for my PT Test. After having been in the Army for several months, I worked on my running on my time. In the US Army, there are standards and men keeping the standards. I worked to be above the standard on my time so I was not being forced or pushed on someone else's time. I learned to enjoy running, and enjoy my trials.
Some music is upbeat. It frames some horrible things in a way that makes it endurable. The song "Jessie May" is a song about someone who went through something hard. It is upbeat, and it is hard not to smile.
