Once you have learned the proper skills for the cold calls, the most important thing you can do is practice. Practice like it is your full time job, because well, it kind of is. You want to be practicing in the car, the mirror, while walking down the street, even if it makes you look a little crazy. And I am not saying to memorize your script word for word, I am saying become so comfortable with it, you can go with the flow of a call without losing your groove.
