This has pretty much happened to all of us at one time or another. 

We’ve  agreed to give a speech and eventually we sit down to write the speech  and then bang – nothing comes into our mind. We draw a  blank. We might know what we’ve been asked to talk about, we might know  our audience, we might know the importance of public speaking, we might  know everything, but still we just don’t seem to be able to find a way  to start our speech. 

What’s a speaker to do when this happens?
