Rigidity is an understandable, yet primitive, fearful avoidance of change. Change that we feel is beyond our current ability to handle & survive. See: http://mindfulnessforeveryone.blogspot.ca/search?q=rigidity
Psychological flexibility, on the other hand, is about bravely opening up to clearly examine & skillfully engage with what's facing us, right now. See: http://mindfulnessforeveryone.blogspot.ca/search?q=Psychological+flexibility
Need for change may be obvious to everyone except the person who is rigidly avoiding change. The rigid individual is unable to fundamentally (qualitatively) transform to a new self-concept / worldview. At best, this individual may think in terms of minor (quantitative) adjustments to reduce stress.
Difficulties, friction, noise, liminality are various ways of experiencing a boundary - a "line in the sand" between our current self-concept / worldview and the one for which we're ready, or almost ready.
Boundaries are imaginary - not solid walls, nor necessarily sources of suffering. A great deal of energy is trapped by trying to maintain old boundaries, which when released, makes this energy available for loving & living.
