I have always been petrified of public speaking. During my VCDX certification journey, the presentation was always my toughest task, I would spend hours and days stressing and freaking out about talking to the panelists. Yesterday, I realised I was cured. Now public speaking does not bother me in the least; no nerves, no second guessing, just the concise delivery of information to my audience. How did this reversal occur?
