In preparation for giving a talk about "IT for emergency physicians" in Kos in september I stumbled upon a great podcast site, The Toastmasters Podcasts. The Toastmasters club needs no introduction but in case you haven't heard about them:
"Toastmasters International (TI) is a nonprofit educational organization that operates clubs worldwide for
the purpose of helping members improve their communication, public speaking and leadership skills..."
Their podcasts are simply awesome and touch everything you have to know to be a good speaker. Preparation and training is the most important thing you do if you don't want to end up standing in front of your audience with a crimpled tongue and your head full of cotton. Now matter how much you've worked on your slides and notes - if you show up untrained, you WILL fail! So enjoy these great and free podcasts where they feed you full of preparation tips.
