You may have read my previous post about overcoming nervousness when speaking in front of a crowd. You will also find another proponent of pre-event rituals in Lisa Braithwaite. She writes about rituals, not only for overcoming nervousness but for many purposes.
You can use rituals for preparation and focus. In this post, she specifically mentions the focusing ritual and the distraction ritual. An excellent beginning in this part one or rituals.
Take a look. Please tell me what you think.
