When you start identifying yourself with your academic achievements/failures, a successful/failed career or even with the image that you are a benevolent/kind person or bad or perverted, that is ego. People generally think that success leads to ego. But on the contrary, ego leads to both superiority and inferiority complex.
It is not the ego which is bad, but the impact which it has on our personality that makes it disastrous. When you start seeing the world through these spectacles, you are full of yourself and this makes you a very proud person or you feel worthless when you are in the company of successful” people.
Many of them are successful in the eyes of society but they are not happy. If that’s the scenario, what’s the use of such success? No doubt, money is important but earning money and running after it are completely two different things. And I am glad that I now understand the difference.
