All people are different so many of us face the same situation – you do not agree with a person so you try to change the point of view of it. You try to prove that you are right but the person is wrong. Did you do it many times? How many times were you successful? According to my experience, I can say that it’s a worthless thing to do. It's almost impossible to change the opinion of another person about something. You will just waste your time and energy. I also know that some of us may become too emotional in this situation and it may lead to quarrels. A quarrel is a worthless thing too because each person will think that another person is wrong. Let's take a family life as an example. How many quarrels do happen because we want to prove something? Lots! I guess we are all forget something very important. It's almost impossible to change the character of a person. You should accept differences of opinions on things and some imperfections of character. If you can not do this then it’s time to leave. I know that it may hurt but it’s much better than wasting your life on things which makes you unhappy and drains your inner energy. There is a good chance that this type of thing happened to you before. If not then I hope you will pay attention to the words I said and will not make a mistake in the future.
