The Law of Attraction:

The law of attraction simply states: we attract what we think about, good or bad.

There has been debate over this theory for a few centuries. 

It is not easily testable because it is subjective by nature.

But consider this:
You were talking to someone and they brought up chocolate cake.
Since the discussion you have been craving a piece of chocolate cake.

If the only thing you truly want to do today has now become finding an amazing piece of chocolate cake, you will likely have a piece by the end of the day.

That is a thought becoming a reality.

Not everyone’s reality, but your reality.  

It begins with the thought that you want a piece of cake.

And before you know it, you are thinking: I need a piece of cake. 

Once a want becomes a need, the law of attraction is a testable law for you.

It still may not be practical or testable for everyone but for you it is.  

When we convince ourselves we need something we have a much higher probability of taking action and obtaining the thing we think we need. 

In sales it is important not to think about what you would want if you were in the prospects shoes, but to discover what they want.

Here is an example
If you are a Realtor and you know a person who wants to sell their home but they are undecided about the timing.

Your job is to tell that person a story they can see themselves wanting to be a part of.
A story that makes them fit into the decision to sell now.

It has to be s story about a real need and a real benefit has to be at the end of the story.
A story in this case should focus on clear benefits that the person would want to be a recipient of.
When  someone experiences the positive benefits from making a good decision, the story they tell themselves about this experience makes them feel good.
Making them feel good and in control of their story is the goal.
It is a goal that has to begin with getting the person to first think the outcome into reality.
Telling good stories to people allow will allow them to subconsciously lead themselves to a desired outcome. 
Regardless of what you sell, prospects need to see themselves in a genuine and true story, told by you.

If you can communicate how a want is actually a need for people you will be very pleased with the law of attraction.
Discover  the urgency and interest a person has in your product or service.

Ask questions and use the answers to start telling them a good story.

Then let the story do what good stories do best...
