Other things I have used include a pen's nib/tip. Now, you need to poke yourself. This might sound weird but this is what happens – as soon as you prick yourself, your mind is driven towards a bit of pain you have created. This is an easy way to cut through any thought you might be obsessing with, helping you put a speed-breaker in the way of Anxiety that usually surfaces with great momentum. I call this the pinch-and-protect mechanism and I have used it extensively – ranging from client communication interactions to managerial meetings.
It usually works immediately and that is indeed the big advantage. You might be thinking about swallowing a Valium or Prozac but they take time to take effect – the pinching game is easy, does not need any tools and can be done wherever and whenever you need to fight the Anxiety Demon!
