Friends and colleagues speak to each using first names only. So do people of authority. They do not call each other and leave voicemail messages asking for Mister, Miss, or Mrs. Therefore, when you call a person you want to do business with and you leave a voicemail message, refer to them by their first name only. Don't say mister, miss, or misses. Don't say their last name. Begin your voicemail message by saying only "hi/hello" followed by the person's first name. Or, you can even forget the "hi/hello" and just say the person's first name. That is how you show confidence and authority and separate yourself from weak salespeople.

A woman calls to report a beheaded squirrel behind a building on Christmas day. She also mentions that a couple kids have got sick due to the headless squirrel. I can just picture this scene.
– Sorry, I can’t be everywhere, and sitting by the phone ready to take your call, just isn’t going to happen. The best thing to do is to leave your message and not be offended that I wasn’t able to speak with you. Thanks.
