Don’t waste your time with explanations: people only hear what they want to hear. – Paulo Coelho
The world indeed has full of stubborn and selfish people who do not give a damn about you or your explanation, when you try to convince them about certain things. However, they create a general misconception about you and judge you according to that.
Moreover, when you try to explain something to people, they will never hear something that they don’t desire or would like to hear. Some people are not open to new ideas or thought and usually did not bother to listen to them, mostly because of their ego.
Therefore, it is a waste of time explaining anything to such people. However, we often try to give an explanation to people; even there is no need and waste our time. Later, when they do not show any interest or do not listen, we start feeling bad for it.
