Humans, unlike Jedi, are powerfully afraid of rejection. We do not survive well alone, so humans as a species are especially vulnerable to thoughts that make us afraid the rest of the tribe will desert us to die a sad, lonely death.
I am responsible. Although I may not be able to prevent the worst from happening, I am responsible for my attitude toward the inevitable misfortunes that darken life. Bad things do happen; how I respond to them defines my character and the quality of my life. I can choose to sit in perpetual sadness, immobilized by the gravity of my loss, or I can choose to rise from the pain and treasure the most precious gift I have ? life itself.
