Breathe, On Purpose
“Forgot to breathe” is a common observation from Toastmasters who are doing a post-mortem about going blank and/or panicking during their speech.
The answer is an on-going cycle of rehearsals and drills and “again, from the top” that put you in the moment when you go blank/panic. Then you can start to add “breathing, on purpose” as a technique to address the moment.
Eventually, you reduce the time-cycle between panic and breathe.
