I don't always remember to use the self-help techniques I've come across over the years. Some fall into disuse only to be suddenly resurrected. This was the case with one recently. It popped into my head again out of the blue and I've started using it once more. This is the smile technique. What I like about it is that it's so simple and easy.
All you have to do is first of all smile. While smiling, think or say a positive thought or affirmation. Then breathe in and out, focusing on your statement. This is very useful for any kind of block you might have or when you are facing a difficult or stressful situation. The beauty of this technique is that you can do it throughout the day, at any time, although there might be some situations where this might not be appropriate. You also don't want to unnerve people with a smile which is too fixed.
It's common knowledge that a positive mental attitude can affect your physical well being but it can also work the other way round. This is what the smile technique does. It employs a physiological stimulus to improve your psychological well-being.
I first came across the technique in an audio cassette course called Opti-Learning by Donna Cercone published by Nightingale Conant. It's well worth listening to if you can get hold of it.
