Not far off from "Don't Rush" is the awareness that worry ruins the life experience.
I don't think I could find many folks who would disagree with this one. Constant worry moves me out of my experience and into a state of discomfort. Perhaps your worry is mixed with anxiety or the feeling of impending doom. That tends to dampen the day.
I can worry about pretty much anything.
One of my big ones is that "I am not doing it right." That one can certainly come up when trying to do my best. What if I couldn't do it wrong? What if just showing up was enough? The more I worry about not doing it right, the less I allow myself to experience just what is happening to and through me.
Life unfolds on its own. I get to participate in that unfolding. Worrying that things are not going right, is like worrying about the way a wave lands on the sand. My worrying won't change it.
So why not just let go of worry and follow the inspired moments one after another. Live your best life by being present to it.
