It says she creates "more for herself than for an audience", and that could be true. That doesn't mean that she doesn't create AT ALL for an audience. It just means that her creations are done more as an expression of the self. A 3 more creates for an audience specifically.
The real world does appear to be less interesting to Amy. She's not what I would call a realist.
As far as a minimalistic lifestyle: She generally did not pursue dating Hollywood celebrities, buying huge mansions, a "glamorous" lifestyle, or any of the other more lavish things materialistic lifestyles offer. She came from a musical family, she was trained to sing, and she got signed. It didn't change the true person. It's not about having money, but how the person chooses to spend their lives regardless, that clues one in to the true personality.
Amy is the true rebel.... the isfp who defies the rules without skipping a beat. She is one who would never change that. She's the one all the wanna-be's, wanna be.
As opposed to:
The six with a seven-wing: The Buddy
Healthy: Engaging and funny, people of this subtype are less serious than the other subtype-- they tend to avoid heavy topics and restrict their focus on their security needs (taxes, bills, office politics, and the like). They are serious, however, about commitments and make sacrifices to ensure the safety and well-being of their family and friends. They also enjoy good company, kidding around, and emphasizing their connections with others.
Average: These people are eager to be liked and accepted, but they are also more hesitant to speak out about themselves or their problems. While sociable, they are also insecure and depend on loved ones for reassurance and advice before coming to important decisions. They have problems with procrastination and initiating projects on their own. They tend to get into diversions and distractions to quiet that anxiety, including sports, shopping, and "hanging out" with others. Overeating, drinking, and substance abuse are possible. They are not particularly political but can be opinionated and vocal about their likes and dislikes. Anxiety about personal failings or important relationships can lead to depression.
The only part that really fits her here is the substance abuse being possible. There's nothing here that gives me any ideas this fits Amy Winehouse, otherwise.
The 4 with a 3 wing: The Aristocrat
Healthy: People in this subtype combine creativity with ambition, the desire for self-improvement and an eye toward achieving goals, often involving their personal advancement. They are more sociable than people of the other subtype and want to be successful and distinctive. They feel the need to communicate themselves and their creative efforts to others, and so they care both about finding the right mode of expression and about avoiding anything off-putting or in bad taste. They create with an audience in mind.
Average: These people are more self-conscious and aware of issues regarding self-worth and how they are coming across to others than people of the other subtype. They want recognition for themselves and their work, and they typically put more effort into everything having to do with their self-presentation and related matters. They are more practical but also more extravagant, loving refinement, culture, and sophistication - typically seeing themselves as high class, elegant, and concerned with social acceptance. They can be competitive and disdainful of others; grandiosity and narcissism are expressed more openly and directly.
She could be a 4w3 gone wrong...... or she could have both wings. But she is one or the other, or both, as I expressed previously. She does seem more 4w5 to me, and a record company helped to develop the rest. I can be very 6w7 at times, as well. I just don't rest there. She seems to be very 4w3 in alot of ways, but she doesn't seem to rest there. She's more of a 4w5 to me who was thrusted into a more 4w3 lifestyle.
End result is: I can't decide between 4w5 or 4w3 lol...... she has clues of some of both, as I do when it comes to 6w5 vs. 6w7. If I had to pick one, it would definitely be 4w5, so I'm sticking with that! I've seen some 4w3's, and they are much more obviously "aristocratic".
