The Art of Public Speaking [EPUB ebook] 

The best way to become a confident, effective public speaker, according to the authors of this landmark book, is simply to do it. Practice, practice, practice. And while you’re at it, assume the positive. Have something to say. Forget the self. Cast out fear. Be absorbed by your subject. And most importantly, expect success. ‘If you believe you will fail, ‘ they write, ’there is hope for you. You will.’
