The 1 Point Technique
This is a great technique to use when you need to overcome nerves, silence that "voice inside your head" or deal with a difficult, challenging, confrontational or even dangerous situation.
It allows you to find a calm and resourceful state, where you are in better control of strong emotions. It enables you to think more rationally and clearly, rather than employing the sometimes automatic response of anger or agression.
A very useful technique to practice - like a muscle it becomes stronger with use.
If you remember to practice it, you will remember to use it.
