Its such a mysterious thing. I just put a define:ego and whoa!! Such a long list ..
To my perception, this one fits the bill
The self, especially with overtones of self-importance; The most conscious part of the mind, which mediates with one's surroundings
The reason, as usual, is in my surroundings. Seeing a lot of things happen due to ego, Clients, Colleagues, Friends, relatives and even mine
For mine not to affect anyone else, I guess need a different level of self-consciousness, a check on self every moment, Am I doing/saying this for some reason or am I doing it only because it affects me?
Lets see how it goes…
