Not sweating it. I'll be eternal via the crap I leave behind on
  the Internet and little bits of me I leave behind in other
  people's minds and hearts. They might never remember my name,
  but little bits of influence already changed them in ways they
  may or may not know and I may or may not ever get feedback on.
  But I know. And when I'm dead, if there's more? GREAT! I hope
  there is. If there's not? Oh well. I won't know will I?
