Complete objectivity is not an option. We are all subjective about the way we respond to 'what is,' whether it's the people we encounter, the circumstances in our lives, or ourselves. What we can do is reduce our subjectivity - what I call 'I see, therefore it is.'
If we are honest with ourselves, we have to admit that sometimes our assumptions and preconceived notions are wrong, and therefore, our interpretation of events is incorrect. This causes us to overreact, to take things personally, or to judge people unfairly.
