My friend who runs our martial arts school regularly says, “Fatigue makes cowards out of us all.”
It’s completely true. Sometimes you’ll run into things you can’t change no matter how hard you work on them. That’ll grind you down to the nub if you let it. I’ve found one of the ways to deal with problems like this is to find a mind expanding escape.
On the way to my job, which I really don’t like, but can’t leave, I let my mind travel. I listen to podcasts involving great thinkers and listen to books about subjects that really interest me. When I walk into the door there, I’m usually not in a pissy mood. My brain is usually engaged and firing.
After a day of aggravation, I listen to those enlightening things again and it engages my mind yet again.
You may be sentenced to life in a crappy prison from time to time, but your mind is free to wander away. Your brain doesn’t have to be in that prison cell with you.
