Yea.you could even pull out a pair of those toy glasses (with the swirly pattern on the lenses), and say "Well my imagination isn't THAT good." as you put them on.and then go "Whoa!". interesting underwear!" (a reference to that classic bit of advice, about "if youre nervous, imagine the audience in their underwear") (This will amount to admitting your nervous, and they'll like you for showing that you're human, plus you'll no longer feel nervous. ALSO: people who are going to give a speech sometimes try and come up with an "opener" to lighten the mood, and make them like you, at the start.) For example (though I dont know if this'd be good, but) you could say, first thing when you get on the stage and have their attention, "well. People hate that.) (*TIP:Jokes are often as easy as taking advantage of a play on words.) (4 or 5 laughter breaks in a half hour speech is a good amount ( I wouldn't exceed it.
THIS will do wonders for the lightness of your presentation (so it wont be all non-stop serious and heavy. That doesn't mean tell knock knock jokes, or "the one about the boy scout and the priest".but any time something you're discussing makes you think of a joke, feel free - within reason - to go after it. So be interested yourself! Somehow.) SECOND: Throw in a bit of subtle humor, every so often.
(And remember, if you're interested, they will be.but if you find what you're discussing boring, they will sense that.
You need to figure out a theme.What about Thailand are you making a point or points of? Once that is known, outline it on cards, and make planning notes on each of how you think it would be interesting to talk of each point, how to present them so they're interesting.
