Ad-Rule No.8 - The rule of Relevance

Here are my answers to the questions I posted earlier today.
Q1-4:
"I bought a spaghetti lunch box form the canteen after the tutorial this afternoon because I knew that my colleagues had gone for lunch so I decided to go to the canteen because it's convenient and it saved me a lot of trouble walking all the way down hill to answer my lunch problem."
Q5-8:
"I saw Visa's "Let's Go" commercial on SlendAd.com this afternoon because I could use it to illustrate the Ad-Rule which I'm going to post to students today."
Visa - Let's Go TVC

Do you see my point here? Well, with the first four questions, I want you to find out the motivation behind your decision to buy the product, and the motivation to pay attention to an ad with the last four questions.
The keyword in my case is "relevance". So what is/are the keyword that can sum up the motivation in your case.

The rule of Relevance tells us that it is essential to create ad that is relevant to the audience. We must provide the solution to their emotional problem. Note that emotion need is emphasized here because we don't sell product features entirely on its own. We need to tap into the psychographics of our audience. We need to care about their feelings and thus emotional connections are important. For all they are consuming now is desire, not need. Great ads are the result where creativity meets relevance.

We have to understand that creating ads that based on customers' need is easy. Why? Because it will be relevant to the customers anyway.  Back in the 50s after WWII, everything was relevant to the lives.  Everyone not only wanted everything but they needed it.  E.g. 維他奶, Pak Fa Yau, 保濟丸.
