Day in and day out we wear uniquely crafted masks. They are the reflection of our dream selfs. There is a fine, almost invisible line between doing something for a reason (ulterior motives) or just doing it for yourself.
Our personality is crafted more less by the environment we live in. We are a product of our environment. The masks are the medium we hide behind from the multitude of and people around us. This is why our behaviors and values change depending on whom we communicate with.
