Life is an enormous and tall mountain. It is beautiful and attractive, but climbing a careless step, we may get injured. It is full of challenges too. We may have to face different kinds of emergency problems, like food, hiking skill and accidents. Moreover, the point we are heading for may be very difficult to achieve, but we should not give up. Even though problems may burst out, we must keep going until we arrive at our point. Eventually, after all the problems have been solved, we may come closer to the mountain top. Very soon, we will arrive. We will be successful and feel satisfied for the great job we have done. Of course, we must feel exhausted after a long journey, but looking backward, it is all worthwhile. So, that is the time for us to enjoy the beautiful scenery on the top of the hill, and to enjoy the taste of victory!
