True. If a speaker is more managed on delivering a speech the less nervous he/she becomes. Following the rules can be a great help to organized the thoughts needed for the talk. It also prevents a person from going to a difficult situation because they already know how to focus. Although the rules can help a lot, do not set a perfect output on lecture or discussion. Remember those good speakers can still feel nervous during the moment. However, do not let the opportunity of public engagement get lost.
