Sit down, close your eyes and remember a time when you felt really confident.
Picture in your mind what you say, hear what you heard and feel what you felt. Now enhance those images. Make the pictures brighter and bolder, the colours richer, the sounds louder and the feelings stronger.
When you can feel a burst of that confidence quite strongly, carry out a specific action like squeezing your thumb and your middle finger together. That will link in your mind the feeling of confidence with the finger squeeze.
Go through that routine ten times in a row to reinforce that link between your fingers and the feeling of confidence. Eventually it will mean that you will only have to squeeze your fingers together and you will begin to easily remember that confidence.
Now think about the event you want to be confident for. Imagine the event going as smoothly and as perfectly as you can while all the time squeezing your thumb and finger together re-triggering that confident feeling.
You will notice a difference in your confidence this time. Every time you do this you send a very strong message to your unconscious mind that you want to be more confidence at that particular time in the future. I have known some people to wipe out a life long fear of public speaking with this one simple exercise.
