What I hope to accomplish is simple: I want to become more comfortable with the idea of death. I want to get to a point where I'm (reasonably) okay with dying. Obviously, I don't want to rush things, but as I get closer and closer to that day, I don't want to be terrified. I want to be able to accept it.
Someday again I will be dying, lying in a hospital bed with only days left ahead of me -- and truthfully yes, if you want to define "dying" as losing a battle to illness then I am in every sense of the term dying... but personally I like to call residing in this defective body, riddled by disease: successfully, and enthusiastically living.
