A person who thinks himself or herself as the superior and believes in his or her own importance. The feeling of being yourself or considering yourself to be the uttermost important than others is called 'Ego'.
There is a thin line between ego and self-respect. When the word 'I' or 'Myself' deeply fits into your mind that's when your self-respect turns into ego. having a ego is not a problem but when someone respects you or is kind to you and you not responding with the same manner, that causes the problem. As long as the ego is in control of you you need not worry about it. But if the ego start controlling you then you need to worry about it and work on to improve yourself.
You may wonder how can this 'ego' affect you. Well, it can affect you in various ways. Not only you it can affect the one with whom you have a strong connection. Given below are some of the consequences of ego
