Trying too hard is something that every good air talent goes through. Getting past it takes a bit of self-realization.
Looking at it in acting terms (because we are all voice actors to a degree), “reaching out” to the camera (the viewer) is the wrong perspective.
Let the camera (or in our case, the Listener) reach out to you. Overperforming is a drag. When you “reach,” it’s exaggerated.
Just settle down. Simply be there and be what you are, and let the Listener reach out to you.
