Three Tips for Speaking in Public
1) Connect with your audience - make eye contact and smile. Positive emotions are contagious; so are negative ones!
2) Be passionate about your topic. The best speakers are the ones who are most passionate about the topic they are speaking about. Remind yourself why what you are talking about is important to you.
3) Prepared your speech. Plan what you are going to say, but be prepared to go off 'script'. Allow for some spontaneity and improvisation.
