A call to action

If you are a host/presenter you should try and follow this rule of play. Topic then call to action. Topic - your churn on a subject, then the phone number, text and email details. How many times have we heard hosts/presenters come out with the line - 'lots to talk about today call me on xyz...' Well what lots are there to talk about? What do you want me to call about? So Topic then call to action everytime.
