In my experience, the most effective thing in creating desired changes is to identify, not ignore, what you are really feeling. But then it is imperative to do the work, as in use the tools, to change it. Complaining and dwelling on the problem are very different from identifying it and shifting it into a higher vibration or feeling.
But most of the time, the entire focus stays on the negative or the problem. And as we have seen through such things as the Global Coherence Initiative, mass consciousness creates a powerful force that impacts all of us.
Listen to what Jeffrey Van Dyk had to say about it. I love his perspective.
