OBSERVATION (depth and breadth)

depth: that which protects you during a storm (- hence the need to ‘go deep’ to cope with a crisis; cf: a storm cellar)
breadth: that which enables an ample harvest (e.g., cornfields)
(And it’s interesting when the two coincide, like the iconic scene in the movie ‘North by Northwest’.)
So: Everyone needs a storm cellar and a cornfield.
