Once upon a time, I learned a great coping mechanism from that ginger-haired fictional heroine, Kimmy Schmidt.
She said that “a person can stand just about anything for 10 seconds.”
So, if you’re in some seemingly unbearable situation, just take it 10 seconds at a time. And once you make it through that 10 seconds, try 10 seconds more.
When life is hard, break it down into bite-size bits. It’s much easier to swallow it that way.
