Somedays, you struggle to run even two kilometers. Your breath is fine, no muscles are hurting, but you just cannot bring yourself put one foot in-front of the other, and to keep doing it.

It is not the legs or the lungs that determine how far or how fast you can run. It is the heart, and only the heart.
Isn't Life like that too?
