#01 - Share with the Audience
If you are concern about speaking to the audience, how about have a paradigm shift - SHARE your experiences; not teach them or tell them what to do. People enjoy sharing stories and audience like to listen to stories. So go for it!
#02 - Stand Firmly on Stage
Which means, placing your weight on both feet - not just on one leg as you may appear off balance (and sometimes literally off-balance!). By having your weight on both feet, you'll naturally feel confident and strong.
#03 - Move with a Purpose
Let's not speak behind the lectern. Rather, move as you speak. Having said that, identify certain points on stage and move to that points as you share the different points of your presentation. By doing that, there is a sense of purpose and confidence.
