There's quite a bit of social theory that backs up the fact that, at the core, people find it difficult to change, but that they are still capable of it.
My experience? Most people HATE change. I relish it. I live for it. Change of scenery. Change of interests. Change of mind-set. Just change. It makes me feel alive and living vs. dead and dying. Even the most tragic things in our lives can instigate change ~ and often times that change is what helps make us better people. More understanding, more tolerant. Much move willing to offer and receive love into our hearts/lives. Without change? We'd all still be single-celled creatures. How dull would that be?
