The quiet art of making something fit that wasn't there before.

means The act of putting one thing into, between, or within another thing — or that thing once placed.

from From Latin insertio, built on inserere — 'in-' (into) plus serere, 'to join or put in a row,' the same serere that gives us 'series' and 'sort.' Latin writers used it literally (grafting a branch, threading something into a text), and English borrowed the noun whole in the 1500s to describe exactly that: slipping something new into a space that already had its own order.
