Ego

 I used to fight a lot when I was a kid. I didn't liked it when people look down on me so I  always fought to satisfy myself. I used to have an image of myself which if altered by someone made me go crazy. This negative attitude is called ego. Ego is something for self satisfaction. We always crave to be the best and this feeling last forever unless you have achieved enlightenment through meditation i.e being one with the world. When we differentiate ourselves from the world we look down on people whom we presumes as inferior. This feeling of superiority is only for self satisfaction and nothing else. Telling people what great things you are doing or showing off is a sign of ego because you are trying to create an impression in front of others. Ego can lead you to down the hill if it goes out of your control but if you use it for self improvement than its a great weapon.
