1. Sincerity – if you believe it then it will be a lot easier for them to believe it. Once you have sold yourself then the rest becomes much more natural.
2. Repetition – saying the same things, the same way, over and over. Be consistent in your words. That way you get better every time you present.
3. Brevity– don't ramble, stay on topic. It is "cause and effect"…the better you get, the less you words you will use and…the more compelling you will be.
4. Style– develop your own style. Watch others, pick up ideas, make adjustments… but always be you!
One way to learn to be a great Communicator is to watch great performers. People like Jerry Seinfeld, Celine Dion, Russell Peters, Usher… they have mastered the above four points. Also, they do not vary their presentation style. To make more sales, to make more money… work hard at your craft… very hard. Stand out, be compelling, be consistent. The rewards are huge. Great Salespeople are paid extremely well! Why not you? NO Excuses.
