Railroad
I think life is like a railroad because life is always is always moving no matter what even if you stay on the past life moves on. So all of the school "drama" and such that seems so important now isn't really because who is going to care about the pencil that you stole from whoever in about 4 years from now. Life goes on even if that one thing or that other thing you just have to move on even if it's not the easiest thing to do because if you just stop moving then your life will be a total crash like a train crash.
