Success & Failure
You will encounter failure on the road to success; to think otherwise would be naive. A heartbeat without peaks and troughs is that of the dead and the stagnant, a valley is defined by the mountains surrounding it, and a sky without ground is nothing more than empty space. In order to know where you're at you must have things that you can reference. Imagine trying to navigate a flat and empty plain with nothing on the horizon to help you orient yourself, nothing to use as a frame of reference for where you've been and where you're going; you will find yourself easily lost. Set yourself a goal to achieve, a mountain on the horizon to keep your focus on and you will never find yourself lost. Without this you will wander aimlessly.
