阅读下面短文，根据短文后的要求答题。In a village near a desert lived a young and successful businessman; named James But he often felt unhappy because of the endless challenges he faced.
One day, a wise old man came to the village with 100 camels. James went to see him and said, "I always have business worries, family troubles and health problems. Please tell me how to make them disappear." The old man smiled and said, "I'll give you an answer tomorrow morning. But first, can you do a small thing for me?" James agreed. The old man asked him to take care of the 100 camels for the night, making sure that they all sat down and rested before he could go to sleep.
The next morning, the old man asked James how his night went. James said sadly, "I didn't sleep at all. No matter how hard I tried, I couldn't get all the camels to sit together. Even if I managed to get some camels to sit on one side, a few others would stand on the other side."
"That's true. As noticed last night, some camels sat down on their own, while others required some effort, and yet many camels did not sit even after lots of effort. If you had come back later, you would have seen that some of the camels, even though they didn't sit at first, finally sat down on their own," the old man said.
James nodded. The old man continued, "Problems are just like camels—some problems get solved by themselves, some get solved when you put in some effort, and some do not get solved even after you have tried your best. Leave such problems to time. At the right time, these problems themselves will come to an end. "
James felt a sense of understanding. It completely changed the way he saw life's challenges.
