YOU are in the traffic controller seat and YOU are the only one in control of those thoughts! Don't take in and dwell upon what you know is wrong, destructive, or untrue. When my children were young, I would explain to them why I would not allow them to see certain movies and read certain books. I wanted them to know that your mind and body is like a computer...what you put in, you will get out. If you put trash in, then don't be surprised when you get trash out. By guarding your mind and allowing only the "true" thoughts in and keeping the "yucky stuff" out, your spirit will be more at peace.
Be a wise traffic controller who stays alert and on guard...only allowing the "good" thoughts to settle securely on the landing strip of your mind. And the next time someone calls you a "Box"...stop and ask yourself, "Now is this a true thought?" If it is not, then as the traffic controller, tell that plane it is too crowded to land and to keep flying!
Then rest securely in knowing that your significance does not lie in what fickle people think...Your search for significance is found in your Creator!
