This is one of my favourite lessons - I remind myself of this everytime I feel uncomfortable.
I know some people who will do just about anything to avoid discomfort - they'll go so far as to fast-forward through parts of shows or movies that "feel too tense". This constant avoidance of discomfort actually makes us more sensitive to it and weakens our resiliency.
What are your thoughts on this? (And please, no shade to my massage therapist. He's the reason I have range of motion and all my ribs are seated where they're supposed to be).
