Over the years, I think, people - actors, writers, whatever - lose their frame of reference. Their frame of reference is based on somebody else who did this or did that. Performances. So it just becomes a reflection of what already works. Like a warm-up. And that's an invitation to be inauthentic.
I remember my mom threatening me, half-serious: 'You know what? I should take you to Pittsburgh and put you in dance lessons just to keep you occupied.' Well, that brought everything to a screeching halt. 'Jeeze, dance lessons.' In retrospect, it would have been awesome, but then, 'Ugh, dancing - dancing's for sissies.'
