Inspiration comes from various sources. Words overheard. TV
  shows when you're kids that come to mind. Something you read.

  How much weight you place on it is totally up to you though.

  If it sparked something in you and you find it an interesting
  trail to follow, then follow it. If it starts to be boring or
  becomes more troubling to you than you want to deal with, then
  you can stop and go think about something else.
