There is a saying about worry that goes, “Worrying is like sitting in a rocking chair. It gives you something to do but it doesn’t get you anywhere.” Needless to say that put simply, yes, this is true.
Then again, there’s another saying that is equally true. “Never in the history of calming down has anyone ever calmed down, simply by being told to calm down.”
I go back to that word, “Just”  and the way people simplify our difficulties when they offer their advice by saying, “Just don’t think that way.”
