"Like any good drug, anger can mask all reality. But anger is not an easy emotion to call up on demand, which is why an enemy is so wonderful. You're tired. Didn't sleep well. You have zero energy. Then you get lucky. You pull into the boathouse parking lot and see your favorite enemy. Celebrate. Your workout is saved. One look at that chowderhead can put you into the angerzone. As you turn off your car, you can feel your whole physical being change. Respiration increases. The dull look on your face is magically transformed into the power-stare of a true rowing warriot."
