It's not until you achieve something you've been chasing that you find out the satisfaction is temporary and all the joy was in the chase. Because you were hungry. You were focused. You were active. The feeling of wanting and striving and struggling made you feel alive. Once you get near the top, you also find out how short your stay is if you lose your hunger and let off the gas. Because someone else is after you and what you want. They'll kick you right off the peak.
