I think we can change everything about ourselves, inside out. I believe that hope makes us come up to the top when despair makes us reach a bottom. Life is constantly changing. Otherwise we can't adapt to what is thrown at us or get what we seek out of life. Jesus is a religious figure and I'm not very religious, but he made some very good points about human nature and relationships that I quite agree with. Mutual respect goes a long way to avoid conflict and escalation of conflict.
