Anyone CAN sell. Literally anyone. I don't care if you are old, young, shy, happy, sad, tall, short, man, woman, introverted, extroverted, nervous. IT DOESN'T MATTER. Anyone can sell.
BUT - There are 3 things one must learn to do in order to sell. (This is true for everyone.)
1. You have to actually solve a problem for your prospect with your offer. (So simple a 5 year old can do it. I'll show you.)
2. You have to be willing to shut up and LISTEN. (Shocking, but most people have a hard time with this.)
3. You have to apply (at least some of) the laws of sales psychology. (You don't have to be an expert at it, and you don't have to apply them all. But you at least need to cover the basics... and anyone can do it.)
That is it. Those are the 3 things almost EVERY sales person that struggles with sales fails to do.
It sounds simple, but it is the key.
If you follow the formula I use and just laid out, doing these things becomes incredibly simple.
