Metaphor Relationship

I think that a metaphor to describe my relationship with the person that I currently like can be compared to a race.  In some races, you have to work really hard at certain points in order to cover some ground.  At other points throughout, you can just coast along and enjoy it.  Then you have other races, where you don't have to work as hard, because you already know things are in your favor and that you will do well.  However, no matter what, you have to have confidence in yourself in those races, because if you can't believe in yourself and throw in the towl early, you're pretty much wasting your time, and everything will end in disappointment.
