We have to be clear what causes people to take action in marketing.
We always think of these "tricks" we are taught but we never think deeply about what actually moves a person to action or inaction.
Someone may feel like they don't deserve to take action.
Others may feel that they are not capable of taking action: "sure I will buy the course but I'm not going to apply it." is what they tell themselves.
And some people feel like the process of learning will be to hard, long and difficult.
They may feel if they take action on this, that they may loose something over there.
If these are the fears of the customer you seek to change, how can you speak to them in a way that makes them feel like they can confidently take action?
To much marketing focuses on the principles already set in marketing and not enough on establishing a benchmark for how the customer really feels at the time.
