This is oddly familiar...
And I dont even own a smartphone!
You resembled it very well. We must master our minds, or else someone else will, or worst.. Something else.
But I guess its a 'powerful tool', and like almost anything else it can be used for good or bad, for better or for worst, depends on what resonates with you.. Its up to us to take only the best from it.
Anyway, loving your work, peace.
