Going on stage is not an easy task. Besides exposing yourself to others, you have to practice your craft and render invisible that technique in every action and word. If it looks staged, the illusion quickly fades away, and the audience cannot connect with the performer.

Forget about the pitching, and focus on the substance that is there to read between the lines.
