So the next year I   37  up for the race. I didn’t do much to   38   except jog around my neighborhood and I had no specialized training, no game plan, nothing. My only goal was to   39   the race.

In life we all have those moments when we   52   ourselves with others. It’s only natural. But don’t   53   them to weaken you. Turn them into   54   and let them lift you up. Use them to show you what is   55  . Live with your dreams and you are a winner!
