Yesterday I presented a training based on Chalmer's Brothers' powerful book: Language and the Pursuit of Happiness.
He introduces us to the 6 Speech Acts and how to effectively make requests, declarations, tell our stories and complete our commitments. This builds trust, our credibility and positively influences how we "be" in the world.
One of the most powerful distinctions that came from our group was confidence. Don't worry about making a mistake! Give yourself permission to be a beginner. It is not the same thing as being "good" or "bad" at something.
I invite you all, as Chalmers Brothers' did to me, to get out of the realm of thinking, "This is good." or "This is bad."
Instead, how about this way of thinking...
"Given the results I say I want to achieve, how POWERFUL is my request/declaration/commitment?"
Never be afraid to declare the result you want, and then step into it to make it happen.
