There are some people who think that ego and pride are the same. This is not true at all. Ego is known to be your sense of self. This is how you view yourself and your capabilities. Your pride is more related to the things about yourself that can make you happy. There are some people who have big egos and there are also some who have excessive pride.
It is best that these things will always be considered to have a better understanding of their differences. Someone who has a huge ego may think that he is perfect. While someone who is proud maybe someone who has truly accomplished something in his life.
The easiest way to understand the basic difference between ego and pride is to look at their how their differences are described in DifferencesBetween.com. This website says ego is "a sense of self-importance which can lead to arrogance whereas pride is a sense of satisfaction". Let me give you examples of each in a few sentences.
