I don't understand all of the "because she is rich" posts at all.
Of course if you have money to afford everything you want makes you partially happy but money can't really buy you eternal happiness or health.
I'm sure that she wasn't happy when she got deaf in one ear and went to shopping to make herself feel happy about it =P.

ayu is a strong person and before she became a star (and even after) her life were pretty difficult, not the most or extreme but she had a lot of hard time going through things.

Her secret imo (besides the money going jokes) are her friends, her songs and the fans.
She feels really happy and satisfied that a lot of people listen to her songs and come see her performing in her tours.
That's what makes her really happy and not just because she can afford almost anything.
Material things can't really make someone truely happy for long (or health at all), with no friend/s or a partner for life and as a singer/songwriter fans that listen to your life becomes very boring and empty and you can't buy things to make yourself happy, or buy yourself something to feel happy about being deaf in one ear/deaf.
