Selling is very much like acting. Some can cry tears on cue. Others can't cry tears even with an onion on their lap. The key to success is to make lots of calls, be yourself and use some of the techniques from those who have been successful. If you have made cold calls for a while you know this was staged. It is not the real world. The real world might be Frank who fully qualifies in 60 seconds. If no interest he is on to the next call. At least he says that is so.
