Sick with fear before an exam or interview?
Try this old Samurai trick- it looks and sounds weird but it really works. If you have to be on stage or on TV it works for that too.
First get a disposable wooden chopstick or a similar size stick.
Next wet both earlobes either with water or spit- just so you can feel them cool.
Then stare in the mirror and shout incredibly loud- anything will do- oi! is pretty good.
Then immediately snap the chopstick and storm off to the exam or interview- you'll be unstoppable.
The technique comes from the Hagakure, an ancient Samurai manual and I think it works because it takes your mental focus away from the interior out into sensing your skin, your breathing and your physical power.
