"There comes a time when the pain of continuing exceeds the pain of stopping. At that moment, a threshold is crossed. What seemed unthinkable becomes thinkable. Slowly, the realization emerges that the choice to continue what you have been doing is the choice to live in discomfort, and the choice to stop what you have been doing is the choice to breathe deeply and freely again. Once that realization has emerged, you can either honor it or ignore it, but you cannot forget it. What has become known can not become unknown again."
