Whenever I would get bored, I would go into the stairwell that led to our apartment door. I took the steps incrementally, jumping off each one in succession, challenging myself to go higher and higher. I would land on my hands and knees, absorbing impact and pain. I never made it up to the second floor, but I did take great pride in what I had accomplished, having challenged sixteen of my foes and overcoming the fear that they had inspired.
