Talking is one of the easiest things in the world. It can be in a form of giving some kind of an opinion or simply criticizing others over their work. On the other hand, one of the most difficult thing in the world is to keep quite and listen. Listening is never easy, especially when you are being criticized; and it becomes even more difficult when you have already set an opinion, in your head, as to what the other person will say.
Whenever you criticize others, thinking that you are better than them, is usually the case you have to ask yourself "If you really are better than them?" Because when you are smarter than others, you want to become even more smarter and you think you don't have enough knowledge; in the same way, when you have more money than others, you want even more because you are scared it is insufficient for you. Like attracts like anyway.
I have associated a story with it. It is directly taken from Masnavi Rumi (Persian book).
A grammarian sat down in a boat. That egotist turned his face towards the boatman and asked, "Have you studied any grammar?"
He replied, "No."
The grammarian said, "Then half your life has gone to waste."
The boatman thereupon felt very depressed, but he kept silent from answering at that moment.
Then suddenly the wind tossed the boat into a whirlpool. The boatman shouted to the grammarian, "Do you know how to swim?"
"No, O good-answering, handsome-faced man!", was the reply.
The boatman then said, "If that is the case, the whole of your life has gone to waste, for the boat is sinking in these whirlpools."
Everyone has got a talent in them; we are born with a unique quality which is different from others. All of us have a clear idea of how others should lead their lives; But none about our own!
One spends his life correcting others but fail to see where he is wrong. Self-development is an ongoing process which only ends when one has died.
"A life lesson is learnt today,
but my life just ended today!"
