Constantly remind myself that I am not immortal. Until my death, I'll try my best to be sane... most likely by doing things that would be deemed insane if there were people around... but there would be nobody else but me... so sanity is whatever I want it to be... but am I really not insane just because I tell myself I am not..? Right now I can say I am sane, because the boundaries of sanity is clearcut with other people around... where is the separation of madness and sanity when there is no one else around..? [spoiler]Wow... Being the last human would be tough.[/spoiler]
