A bead of sweat runs down your forehead. Your muscles are letting you know the effort you're putting in with a deep, burning ache. Your breath is coming in and out in short, hard puffs. But your mind is focused with laser-like intensity and your technique is flawless. You can still hear the taunts of your buddies as they challenged you to this competition, and there is just no way you're going to let them win. The intensity of the activity is up there, but you'll love knowing that it wasn't easy and you came out on top anyway. And when you do, you'll let the world know that you're ready to take on whoever is next. The competitor in you has officially come out to play. It's you vs. the world.
