I feel that being objective (seeing actions as separated from person) is really important. For example, instead of thinking in terms of WHO made us angry, we should think of WHAT HE/SHE DID which made us angry.
Being objective = not judging. Judging is never fair; A person's qualities cannot be decided just by a single decision he/she made or an action he/she took. A human's life is too long to determine his/her value through short amount of time. We dislike being judged, so why do we judge others?
Judging takes away our ability to value people and be grateful for what they have done. By judging, we tend to capture more negative sides of people. Besides, it is a tiring thing to do. Plus, judging makes us overly conscious of our own actions, which may lead to anxiety.
As practicing objectiveness makes us separate our actions from our self, it allows us to forgive ourselves for our mistakes. At the same time, it lets us put down our egos and make our lives easier.
Let our actions be independent, not part of our worth.
