Some words are better than others. Some words are stronger and more evocative than others. When you are on the phone with a prospect, you have about 10 seconds to grab and hold your prospect’s attention. If you do not do that within that first 10 seconds, your call is more than likely over.
There have been many, many books and articles written about the art of creating rapport with prospects. Usually what it boils down to is being as like the prospect as you can be without mimicking or imitating them. When you are able to do this well, your prospect will see you as being like them. That prospect is then more likely to feel comfortable with you and want to spend time with you and do business with you.
