Knowing the truth about using self-talk is the most important key to opening the door to living blissfully. According to a study in 1911 by neuroscientists Dr. Henry Head and Dr. Gordon Morgan Holmes women who wore large, tall, feathered hats as they walked through doorways ducked their heads even if they were not wearing a hat. The women were so accustom to wearing tall hats, that even when they weren’t, their thoughts still dictated their actions. There was a direct connection between what they thought and what they did.
