Your ego wants to protect you from getting hurt emotionally. So it makes you do things and see things to protect that from happening. The problem is it keeps you from facing what you must to get rid of your fears, prejudices, jealousies, and limitations and from being free.
We all have to look through the lens of our own ego. But turning our attention back toward ourselves to question this filter all our experience passes through and is created from, is far more productive than trying to make the world fit through our ever narrow definition of what makes us happy and why.
