" We all pay dearly when people respond to our values and needs not out of a desire to give from the heart, but out of fear, guilt, or shame. Sooner or later, we will experience the consequences of diminished goodwill on the part of those who comply with our values out of a sense of either external or internal coercion. They, too, pay emotionally, for they are likely to feel resentment and decreased self-esteem when they respond to us out of fear, guilt, or shame. Furthermore, each time others associate us in their minds with any of those feelings, the likelihood of their responding compassionately to our needs and values in the future decreases. "

― Marshall B. Rosenberg , Nonviolent Communication: A Language of Life
