Maybe I'm up too early, but I have an idea: Where will you be in your life when those stars collide?
Write down (briefly) where you are in your life right now, on a blog, Facebook, or even some tweets.
Then write down where you think you'll be in your life in the five or so years when these stars collides. Hashtag it #whenstarscollide or give it a similar title so people can find it when the times comes.
