So forth, so on, so, what not

I know every region has their filler words that they like to use when a person doesn't have anything else to say. I finally realized that the words here are so forth, so on, so and what not. I was in a presentation a couple of weeks ago and I heard one of those filler words or statements in every sentence. I was looking at the customer wondering if he was thinking "if they say that one more time......". We tend to use them when we get nervous or what not. It seems like we also use them when we really don't know what we are talking about and so forth. So.....I decided to start watching what I say because they can really sneak up on you when you least expect it. So I am going to make changes starting today and I'm going to say what I mean and so on.
