On most worlds I go to, I leave behind an instance of myself, a shard.  I perform odd jobs doing anything that keeps me in contact with people and gives me new experiences.  The first time I did this was on New Earth, the first time I left.  I have been there ever since, and every time I return we share memories.  I am a bus driver there, taking people where they need to go, to work or home or play.  I love watching people live.  I love that job.
