If you're looking for a boost of confidence for public speaking and business presentations, think about using W words. Here's how it works: When you feel yourself talking too fast or speaking in monotone voice, try pausing and starting your next sentence with a W word. For example, you could say "WHAT I'm hearing from customers is..." "WHY it's important is..." or "WHERE we go from here..." When you begin a sentence with a W word, you stand-up or sit-up straighter, speak with more energy, and sharpen your message. It's a simple technique that you can remember and use under pressure.
