Speak With Power And Confidence By Patrick J. Collins

A comprehensive guide to improved communication skills, "Speak with Power and Confidence" offers tips on everything from preparing for a speaking engagement, to sitting down for a job review with your boss, to speaking before a courtroom, with the media or in a job interview. 
It will teach readers how to grab the attention of an audience with their first few words, how to deliver presentations that help close a sale, how to gain the upper hand in any negotiation and how to convey a positive, professional image in job interviews. 
"Speak With Power and Confidence" will equip readers with the ability to turn on their charisma and self-assurance to mesmerise, whether they're addressing an audience of one or of one thousand. Most importantly, the book gives readers the secrets to gain absolute control of their image, their message and their audience.

Much of what this book recommends will probably seem like simple common sense, but as an easy way to start thinking through the different elements of effective public speaking, this book does a decent job. I wouldn't consider it the tried-and-true Bible of public speaking, an all-authoritative declaration of what strategies will and won't work, but in general the principles offered will improve most people's speaking ability if applied. The chapters are broken down by different speaking events so the reader can focus on the types of speeches that he or she is likely to give and ignore the less relevant chapters.
