We process and view life through the lens of our own experience. Our environment growing up, our values, beliefs, teachings and personal ethics all shape our opinion of the people and events around us.
The problem comes in when we only see life through the lens of our own experience. We all could benefit from each of us getting outside of ourselves and viewing life and events through the lenses and opinions of others. After all, each of us has something valuable to add to our collective experience.
