I don’t really know what to do at this point, as far as leaving is concerned.
Like, why should I ever have to leave?"
“It’s like nobody thought to do it that way,” he explains.
“Because it would seem like a hindrance in your career or something, like you’re stuck.
But, for me, it’s the exact opposite.
It’s always been a thing that makes people want to have me when I’m unattainable.
So it’s worked in my favor to be busy 10 months of the year.”
