Opposites.

As an actor you need skin as thin as glass in front of the camera and thick as leather in the movie business. 

Finding an opposite can help you see what the thing is and what it isn’t.

Asking questions allows an answer which in turn allows the opposite answer.

Opposites can unearth your imagination.

When writers ask the question ‘What if?’ they’re looking for opposites.  

Raising the opposite can be useful at the beginning of your work when assumptions might be made that haven’t been given enough consideration.

What’s the opposite challenges you to defend your position.

Story is filled with opposites. As is life. Young and old, birth and death, love and hate, good and evil, rich and poor, female and male, language, nationality, religion, etc.

When we say drama has conflict - opposite is inherent in the conflict.

Aristotle, in his Poetics, defines peripeteia as ‘A change by which the action veers round to its opposite, subject always to our rule of probability or necessity.’
