There was a park near my home. But I didn’t go there very often. Many people said there was nothing special. One afternoon I went into the park and found it was really small. I walked quickly because there wasn’t much to see. I walked for some time and found myself standing in front of two paths. 71  I found that the two paths were different from each other.

The left one was wide and clean. There were lots of flowers on both sides of the path. Though the flowers weren’t very beautiful, they made me feel good. I decided to take this path. But wait! I looked at the right one. The path didn’t look nice.  72  Grass grew everywhere. For a long time I couldn’t make up my mind.

  73  It wasn’t nice , but I didn’t want to give up. At last, I came to the end of the path. Ah! There was a small garden there. It was beautiful, perhaps the most beautiful garden I had ever seen.  74  

Many people told me that there was nothing much to see in the park. Now I’d like to tell them that if they had followed the right way, they would have felt differently. But when I told them about what I had seen in the park, they just smiled at me without saying a word. I knew they didn’t believe me. They couldn’t even remember that path because it was so small.

  75  Don’t be afraid to choose a different path. You may get a big surprise!
