A lot of what determines success or failure is NOT the obvious stuff that you see and are concerned with.
Studies have shown that whether you're talking to someone on the phone, or in person, their impression of you & what you say is based ONLY ABOUT 8% on the words you use!!
The other 92% is your body language and the sound & qualities of your voice. I'm sure it's easy for you to understand that if you sound uncertain, no one is going to follow you. To be successful, you must sound and look like you know exactly what you are doing.
The more time you spend learning about the intricacies of your business, the more certainty you will have when you talk to a prospect. And as you study & gain the ability to answer their questions, you look to them like someone who really knows what they are doing.
And when they see you that way, it's a big key to their desire to work with you.
This is something you just cannot afford to shortcut. Write down what strikes you as really memorable, really useful. Talk about it out loud. Tell what you really like. Again, write down your notes.
The better you get at this, the more confident you will sound when you speak with a prospect. When they can hear in your voice that you are certain you know what you're talking about, you are in good shape and you will be seen as someone they want to work with.
