Gym

       Once upon a time, human got tired of outdoor exercise and then invented machines to help them work out. After years of improvement, these artificial physical challenges have become very popular. I am one of the big fans.
       One of the main advantage of the challenges is that you know what is coming up by looking at the monitor. Thirty minutes remaining, you are riding bicycle on a uphill. The machine has to be running at a certain rate, or a warning shows up, which means you have to work hard on this artificial challenge.
        Fifteen minutes remaining, you are half way there. Now you think, "I am tired, should I stop?" You can go play with the running machine for a little bit and then come back to continue on the rest, or maybe a mouth full of fresh water is good enough to recharge your energy. Temptation, temptation...
        Eight minutes remaining, apparently you didn't stop at fifteen minutes because of too much hesitation. Giving up at this point is sort of meaningless. You have been riding the bike for more than twenty minutes, you can totally handle the rest.
        Five minutes remaining, you are exhausted. "Holy molly, I am dying!" You think, "oh well, I can do this!" Disregarding how much you sweat, how bad you smell, how thirsty you are, you keep going because you have a belief.
        One minute remaining, you see hope, future, and happiness. Your head is running a script saying thank you to whoever contribute in your achievement. "I thank my mom and dad giving me a healthy body; I thank my friends being supportive and encouraging; I thank my neighbor's dog not biting my legs off..." Right before this significant moment, everything becomes dramatic.
        Congratulations! You have reached the top of the hill! Tears, sweats, and saliva mix together. You are so happy that it's finally done, and you forget you look supper-dupper ugly right now.
         I looked at myself in the mirror. I laughed. Silly me, I only achieved a fake challenge, not real.
