300 Hurdles Now comes the first hurdle. __1__ We all make it over this hurdle with ease. This symbolizes. Those obstacles in life that we struggle to get over, but we always manage to do so. You can look at that hurdle in two ways: "I can’t make it over, I’m too tired" or "I am one more hurdle closer to finishing this race". This is an example of taking a negative situation and seeing something positive in it. The next part of the race is every hurdle between the first and last one. __2__ This happens a lot in life too. There may be a situation that arises where you feel as though you can’t make it and all you can think about is giving up. You may fall over that "hurdle" or struggle getting over it, but somehow you find it in yourself to jump over it and move on with the race. Next is that last 100m of the race. You feel as though you just want to say, "No I can't do this." __3__. Now lastly is the last hurdle. This hurdle is the toughest out of all of them. In life we find ourselves falling and falling, and maybe getting too lost in our problems that we fell like have been though enough and there’s no hope. __4__ It's one step close to the end of the race. Once you finish, you look back on it and you realize that you made it not by leaping, but step by step. "Yard by yard, life is very hard. But inch by inch, life can be a cinch."__5__. __4__内应选()
