I would say that the box does exist as territory, as the realm of cached human thoughts. However, what most of us perceives as 'outside the box' in our maps is, in reality, 'inside the box' in territory.

So, essentially, the way forward is to attempt to make something 'good' rather than something 'original'. Because of cached thoughts leading all forced 'original' thoughts into truly unoriginal thoughts, the only way to make something truly 'original' is to make something new, not through the attempt of making something new (which would lead you in circles), but to make something better than the rest. By trying to make something better than the rest, it has to be markedly different from everything else.
