The I’s have it:
Imagination sparks ideas; inciting invention, or at least innovation. Ingenuity, once inflamed, illuminates the way toward the next, higher iteration of inspiration.
A spiraling interval, rarely is it so ill-fated as to be infected with inertia or encumbered by inaction.
Should such be incurred, use it as merely an intermission, an interlude for introspection; from which to emerge indomitably invigorated.
