It is important to remember that a thought is harmless unless we believe them and act on them. As the subject, since thoughts are an object of your awareness, you have the power to challenge every thought. You can decide if you want to make that thought real.
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.'
We perceive through our senses a person, a situation or an event, and in an instant, we project our mental models - our fears, background and experiences - onto that perception. This often results in cognitive errors, which means we judge and respond incorrectly.
The truth is many of us have been socialized to think that if we are not the very best, if we are not at the top 1 percent of whatever it is we do, then we are not good enough. To reinforce this already pervasive mental model, society has established a competitive hierarchy for just about everything.
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.
