To me there are several types of fishermen. One is there to catch fish at any cost. This persons stress level will rise the longer he goes without catching a fish. Another is there to test his skill against a worthy advisary. Thus catching the biggest fish and once more proving his worth as a fisherman is important to him. Another is there just to get away from it all and to enjoy the quietness and experience what the day has to offer. If he catches a fish its a welcome bonus but not the most important thing. I always try to be that third person but usually its a combination of all three of them.
