What is the summary of the poem reality by konai helu thaman?

The persona is growing fast now as an adult. He graduated from school but overall he isn't smart as he already graduated. He has been unemployed until now then his people are laughing at him cause he's quite well in school but still can't earn a living. So there's a market around his village but he doesn't want to be one of them doing stuff like selling some different stuff cause people around him just laugh at him. So after that, he saw his teacher who encouraged him at school sitting on a sterile rock near the beach by selling green coconuts then he was confused about what he gonna do next. After that, an old man went to him and whispered to him that he should go with him and fishing cause there were many things to learn soon.
