What I have to say in this video is a variation on the general theme of being present where you are. In this case pointing out the wisdom of listening to ones own words while speaking. Not a bad plan. As a singing teacher said to me once, I tell my male voice choir that nothing should come out of your mouth before it has been run through your brain! So even before one gets to the audio, wise thought – is wise.
Please note I have not developed a lisp, what you hear on the video is temporary and more to do with technology than a speech impediment.
