Honestly watch the videos, he's exactly right. I worked in sales and it's true 99% of the battle is in your own head, you go into a meeting thinking they have all the power and they are big and you're small, they have what you want (money to buy, the job you want) and you feel like it's a battle to get them to give that to you.
People buy with emotions and justify with logic, so what he does is get them into an emotional state by getting them talking about their problems, then getting them to give examples of those problems, so they're thinking about those problems - then explains how he has the solution.
It's boring explaining it in words, if you watch what he does - everything he says is for a reason, and it's kind of like an act.
He is a literal genius when it comes to getting what you want from a meeting. All of your competition will go in and talk about themselves, I do this, I do that, this experience, that experience, blah blah, all the same.
If you answer their questions with a question (like he shows you) to get them talking about them and their problems you'll walk it.
You'll definitely feel more relaxed because you'll have a plan and know where you're going to take the conversation.
Good luck anyway, I'm rooting for you buddy.
