I have literally in my life given thousands of public speaking engagements. Despite this reality there is always that moment of self doubt before the presentation begins. That little voice at the back of my brain says”is this the time you are going to bomb?That moment of self doubt is natural ,and exists in most life experiences. However, in my case it has always passed and to have self doubt is most natural. The only negative is when the self doubt takes over and makes what we seek and desire unattainable. That voice that is most times purely negative is also the voice of opportunity if you pass through it.
