Reflect on This...

I am willing to put myself through anything; temporary pain or discomfort means nothing to me as long as I can see that the experience will take me to a new level. I am interested in the unknown, and the only path to the unknown is through breaking barriers, an often-painful process. --Diana Nyad


Question:
How do you deal with the temporary discomfort that happens when you are in danger of stretching your comfort zone? What process, mechanism, or ideal allows you to perservere past those initial growing pains?
