One of the first lessons running teaches us about success in athletics and in life is that there is no one else. No one else can do your workouts for you. You alone must do the drills... You cannot hire someone else to do your cross-training when you are battling injury, or pay someone to run a race and get you a new PR. You are truly your own hero in running. It is up to you to have the responsibility and self-discipline to get the job done.
