Now, here's where the embedded commands begin. I don't know if you've ever heard of Neurolinguistic Programming, NLP. I'm no Ninja at it, but I've learned a little bit about it through the years and if you can embed commands that aren't direct commands, not explicit, I'm commanding you to do this, but a subtle statement of a thing that embeds as a command to your subconscious mind, it can have an influencing effect on the other person.
2.) A gracious phone message is 30-45 seconds when talking to those we don’t know well. As George Washington said (yep, that George Washington), and I’m paraphrasing, “With men of business, be brief.” Be pleasant, and get right to the point. You’ll appear more confident and capable of handling the situation which merited the call.

I have a confession to make: I haven’t recorded a new voicemail greeting since 2014. In the past four years, I (hopefully) have become more articulate, poised, and self-assured. But hear my voicemail recording, and you’d think I was still new to the work world, a little unsure of myself — and probably not an authority. Obviously I need toupdate it. And if you haven’t changed your voicemail greeting in over a year, you’re likely in the same boat. After all, a professional voicemail recording boosts your credibility, makes you seem more competent, and encourages whoever’s listening to it to continue the relationship. A relatively unprofessional one — like mine, for instance — does the opposite: It encourages prospects, recruiters, and potential connections to run in the other direction. With that in mind, I’ve written 18 unique voicemail greetings for every situation. Pick your favorite, practice a few times, then record your new voicemail.
