Sat Nam, Wahe Guru, everyone! This is a useful article, indeed. It brings to mind, the old saying, "Birds of a feather flock together." Spending lots of time around critical people may not be a great idea. Attempting to change a critical individual's behavior may not be very successful, either. There is another saying, "It only takes one psychologist to change a light bulb, but the light bulb really has to want to change."
