What I do is stay busy. It really is a matter of shifting focus. It’s a conscious choice to focus on what is around me NO MATTER WHAT.
Life throws you a curve ball---you can rant and stamp your feet; or, you can do something creative. Something that demands your full attention---when your mind wanders, laugh at yourself and hit the mental RESET button.
Will you stay out of your vexing brain today and best the fear of change?
