What are the risks of not adequately rehearsing for your next presentation? Well, let me ask you, what's the risk of sending a cover letter or a resume to a prospective employer and you didn't spell check or edit it? That's right. You can have typos, misspellings, and you can look like a fool and make a horrible impression. No, it's exactly the same when it comes to rehearsing your presentation. If you haven't rehearsed your presentation on video and actually looked at it to say, that's exactly how I want to come across making sense. If you haven't done that, then you're no different than someone who sends you a cover letter and a resume filled with typos and spelling errors.
