hints:
blade
A few minutes later the student came back. The teacher asked, "Well, I don't see a beautiful blade of grass in your hand." The student said, "On my journey, I found quite a few beautiful blades of grass, but I thought that I would find a better one, so I didn't pick it. But I didn't realize that I was at the end of the field, and I hadn't picked any because you told me not to go back, so I didn't go back." The teacher said, "That's what will happen in real life."
幾分鐘后，學生回來了。 老師問到："我看你手上沒有漂亮的草呀。" 學生回答說："我在路上發(fā)現了許多漂亮的草，但是我覺得我會找到更好的，于是就沒有把它拔下來。但我沒有意識到我已經走到了草地的盡頭，因為你告訴我不要往回走，所以我一顆也沒有拔。" "這就是生活中經常發(fā)生的情況。"老師說到。
