When you feel pain, reframe it. It’s not your pain; it’s the world’s pain. It’s the pain of someone else, someone who probably isn’t as strong as you. And just like you would offer to carry grocery bags for someone who is obviously infirm, you should be grateful for the opportunity to carry that pain. Simply imagine that to do so is to relieve someone else’s burden. “Here, let me carry that for you.” It’ll still hurt, but you’ll bear it much more gracefully. And you’ll grow.
