Get there early… lay your stuff down at the front… walk around and greet people. Shake hands and ask questions to hear some of their stories… “what they do, why they are here today”, just connect. Get your mental focus off of your self and do not even mention you are a speaker unless they pick up on it.
15 min before .. get alone. Ask the Spirit for his words in your heart, and breathe in through nose and out through mouth slowly and deeply 5 to 6 times as you pray….
