Refaeli was a VERY talented painter. He loved to paint and decided to use his talent to make money by sharing it with those who had an appreciation of (his) art.
Was he gaavadik because he knew he was good at it and decided he wanted to do that for a living?!?
How is that any different?
Men can Daven for the amud. They can share the beauty of their voices publicly. Why are they any less gaavadik?!?
There is nothing wrong with her recognizing what she is good at. It doesn’t mean her self esteem is built on that or that she thinks she’s any better than anyone else.
Is a teacher gaavadik because he’s good at teaching children? Would you insist that a teacher chose that profession because he liked hearing the sound of his own voice??
I don’t think most people would choose a profession with a low income just to hear the sound of their own voices.
