I have a presentation to a bunch of senior people today, on a subject I'm not as au fait as I want to be.
I'm not great at delivery, I always seem to hear my voice cracking but apparently it doesn't. Any tips from the experienced presentation givers bar the "picture them all nekkid" ones.
Practice. Practice. Practice. I know it's obvious, but the more you become happy with the presentation the easier it becomes.
Also, as hard as it is, film yourself. Analyse yourself, and practice some more.
I present a lot, often to large groups of people (100+) and to senior managers and CEOs of businesses as well as government. I still get very anxious about it. But I practice. In smaller meetings, I look confident because I have practiced so much, and people say to me "how to you appear so natural?" - it's about story telling rather than reading a script/reading powerpoint slides. If you can tell a story (it doesn't have to be funny, just engaging) and practice the right use of rhetoric you'll be able to create a more interesting presentation, but also you will feel more comfortable telling a story. You should and must include relevant facts, you could use Cicero's rule of 3 approach for more poignant points.
I have a stack of useful info at the office I'll have a look and see if any of it I can share.
