For many people, public speaking is a very traumatic thing.
It is not something that has ever held any great terror for me. That
is especially true now I am totally blind.
My Public Speaking Rules
These are some rules I live by when public speaking. These apply to
things like technical talks or lectures. Not necessarily to after dinner
speaking, or the speech you might give as the best man at a wedding.
Those things are different entirely:
NEVER start a talk with an apology for being a bad public
speaker. You will be implanting in the audience the subconscious
suggestion that they are about to sit through a talk given by a bumbling
idiot with limited knowledge of the published subject.
Three part rule. A talk about a technical or serious subject
should be divided into these three parts
- tell them what you are going to be talking about
- the meat of the talk
- summarise what you just told them.
This was given to me a very long time ago by a retired lecturer from
the London School of Economics.
The people in the audience wanted to be there. So there is little
or no hostility in the room. And much empathy.
Don't rush yourself. Pace the talk. Rushing can be a nasty
feedback loop which makes your pace increase and your level of
Don't be afraid of pauses, or silence. These moments can give you
breathing space to summarise in your own mind where you are at, whether
the last thing you said needs amplification, and what is to come
Don't be afraid of the 'ums and erms.' But keep it to a minimum.
Silence is better than verbal ticks.
Keep humour to a minimum. Depends on the kind of event. If you
are the best man at a wedding, you are supposed to inject humour,
probably at the expense of the groom.
You don't need to pick out one audience member to talk to. You
are just as effective if you are focused on the back wall. Talking to
just one member of the audience, particularly if they are right at the
front, is probably not a good look. Glancing round the room helps to
make everybody feel included.
I probably broke some of my rules, in particular inserting verbal
ticks early in the podcast. I think I improved focus as I went on.
I inserted some humour, including some comments about my family
Christmas, but then it is, well, Christmas.
I am almost never happier than when I am learning new things.
I am fiercely proud of, and amazed at the amount of things I know
about a lot of subjects. I am a knowledge sponge.
The one thing that does make me happier than learning, is sharing
what I know. Which I often do in a tone which suggests I am just amazed
at the fact I know this stuff at all.
Remember, the things you don't yet know are more important than the
things you already know. That is true for everybody. So share your
knowledge in good spirit, keeping arrogance out of the picture.

A "must listen" to all who aspire to speak to an audience
This is a great list of tips for public speaking.
A couple of thoughts, prompted by this episode...
I have given talks to hostile audiences, or at least audiences with some hostile attendees. I have given talks where there are attendees that are only there owing to having been told that they must be there (typically by their boss). Body language usually gives these people away. Once they are recognized as hostile, they can mostly be ignored, allowing the speaker to focus on the people who indeed have chosen to be there. However, the hostile attendee is very rare.
I have found, when including humour, it is best to avoid a pause after the humour is delivered. There is a tendency to pause to allow the audience to respond with laughter, however, if the humour does not succeed, the pause will be very awkward. It is much better to go straight to the next statement after the humour. If the humour worked and there is laughter, a pause mid-sentence (post humour) is fine. Start the interrupted sentence over when the laughter diminishes and all is good. If the humour did not work, the lack of a pause allows the audience to continue listening and often not even notice that there was a unsuccessful attempt at humour and the speaker does not suffer the embarrassment of appearing to try to be funny. Pauses are good, but tricky when they follow humour.
Just some thoughts from listening to this very good episode.

Thanks for sharing.
Very well presented, Mike.
I personally enjoy public speaking and teaching, but I was still able to gain some nuggets of wisdom from your podcast. Even after years of speaking, I still struggle with omitting "Ummm", "Uh", etc. These usually happen if I lose my place or am trying to work away from my original outline or answer a question. I like your idea of pausing at these times while I gather my thoughts. I will try to apply this soon!

Thanks for preparing the context for me to shout from the audience : " ! hooray ! ! Moonbouncing ! " .

Thanks very much to everybody. I listened back to this when it was published. I hope the Christmas b
A couple of verbal ticks, but not too many.
Humour is best left out of tech talks, unless you can poke gentle fun at yourself. I was told several times by a writing coach to make my mind up whether I was writing something serious, or something funny. Because the injection of a joke can pull the audience out of deep thought about what you are saying or writing, which might be totally inappropriate.
I particularly like the three part rule, thanks to the late and great Peter Hopwood, once of the LSE for that, some forty years ago.

Messed up that last comment
I messed that up. It was meant to say I hope the Christmas beer didn't make me break my own rules.
