|Yes, this is a great post for all of us. I believe we all do some of this now and then. Some of us are better at it then others. Sometimes when talking we are afraid to pause before moving on in our speaking. At least in writing, we can take the pause and reflect.
I don't like to pause (especially on phone), as you can get over taken by the other party and lose your train of thought. One must stay focus, keeping eye contact if speaking to a group. Maybe this is why, at least for me, when I see or listen to a good speaker, I notice they move, walk a little still speaking, maybe slower, but they stay on track.
They say, don't look at your notes (what good are they except to review before hand). I say, know your material and stay on subject.
Your obsession of being right, that is hard. If you know your material, and the Bible if that is topic, I believe is truth, then you just need to know your material. There will always be those who will attack you and make you think you don't know or have the truth. If it is not truth, then it is matter of opinion, right?
Best to you,
