I am afraid to die.
Have you pictured your death? I have. I want to die dramatically. In a car accident or something --I am terrified of pain, but I am more terrified of not having a memorable way of dying. Illness is boring; I do not want to be an example of strength and courage for others to follow and live on. People don't care who you are, but what you have done, and I am scared that my footprints on this planet aren't enough.
I guess I am more afraid of failure after all.
