When he saw coconuts high up in trees, he wanted to drink coconut water. He thought about how he could drink them for a while. He thought he needed to climb a tree, so he practiced climbing trees for many days.
After he learned how, he climbed a tree and drank coconut water. Then, some guys came to the tree and said, "Please give us the coconut water." He thought that I had made an effort in order to get them, but they tried to get them without any effort. So he said that, "You guys should practice climbing trees if you want them. No effort, no gain."
