My blunt sense impairs the self respect in the infinite competition and loses the meaning and object of competition. This environment makes me lethargic. But the car tries to get stronger in the intense competition and looks for a direction of goal to find the ego. Repetitive new challenge arouses my running instinct and the competition regarding death and survival leads me to a new place. 
But a path somebody has passed is a meaningless repeated challenge. Insensible goal makes me lose the object of competition and groundless competition makes me lose the future destination and wander. I arouse myself to find the direction for destination. Although the direction indicates the lonely fight with myself, I choose the lonely navigation looking for a new direction. I navigate to 7 unknown worlds which may exist somewhere without compass. I make challenge toward my own destination looking for the direction by my own sense. The effort of constant ego-finding changes my environment and develops me. That change excites me and makes me an enterprising traveler exploring the unknown world.
