I always hated public speaking so had the terrible plan to study this not so sexy topic for 8 years. I never got over a fear of public speaking but I did learn to manage it, and ended up with a talk featured on TED.com, recording a standup comedy special and getting regularly paid to speak. Long story! Happy to answer any questions here and I have tone of tips and resources around this topic if anyone could do with a hand. Please ask me anything.
Course wise I put everything I learned the hard one in one online available at hackingpublicspeaking dot com. It's public speaking without the same old recycled waffle most folks try and teach
