This is the part where folks always get it wrong. You can't "give" anybody the "wave", they've gotta take it or themselves. You can put people in a position to succeed or reach their potential but they (and luck) ultimately defines what that potential will be. Some people just don't have that "it" factor.
The "it" factor is one of the BIGGEST myths in social history...
You are essentially telling me that out of 7 Billion people on Earth on a very selective are born with the "it" factor to be pop icons?
Here is a real SCIENTIFIC example, there was a time in human history were people believed an "it" factor (genetics) played the most important role in human health, but then research showed modifying the environment and people's behaviors had a FAR GREATER impact on human health...
I will bet everything I have, and say that the same is true for pop culture MOST things in human society..."Putting people in a position to succeed or reach their potential" are MUCH STRONGER than this mystical "it" factor that you referred to...
But let me say I agree with your "it" factor assumption...
(1) It is clear that pop success involves a team of people working together to attain it...You have the artist, management, marketing and etc working together to achieve this success...
(2) That means every member of the team has his/her own "it" factor...So, how do you decide which team member's "it" factor is the best determinant of overall success?
For example, somebody may say that Memphis Bleek is not as famous as Jay Z, because he doesn't have that "it" factor, but how do you know that Memphis Bleek would not be as famous as Jay Z if he had a marketing rep who had the required "it" factor to push Memphis Bleek to the next level of popularity?
Other examples, why did it take Kevin Hart such a LONG TIME to blow up, are you saying that he didn't have the it factor 15 years ago when he was grinding? It doesn't make sense...
(3) My conclusion is that a COMBINATION of "it" factors are more predictive of success than an individual specific "it" factor...People DO NOT become successful on their own...The environment is very predictive of relative success...
Drake was a child actor, his dad and uncle are accomplished musicians...He didn't come out the blue...He was in a better position than the vast majority of people seeking the same success...
