Dien,

Exactly.
Carnegie Example is a model here.
Just imagine that you are to get a lunch with Warren Buffet to present your idea of uncommon investment fund.
What are your chances to do it directly?

Story #1
There were two "marketers".
One was directly selling his widgets $5 apiece to his lists.
With mediocre results.

The other was targeting INDIVIDUALS, seeking orders of 1,000,000 widgets.
The higher he aimed, the lower were the chances to DIRECTLY make it through the door.
So, the winner contacted the man who was responsible for huge orders through their mutual love - dogs.

Story #2.
(Heard from a World War II survivor, who was captured by Nazis).
He was beaten on a regular basis.
He noticed that the man who beat him had a dog collar in his pocket.
During the ordeal the prisoner kept talking about how smart the dogs are and how he loved them.
When everything was over, his offender whispered to him:
"I was doing my job. I didn't injure any of your internal organs. Why? We both share the same love".
