the.com/foot in the door

The smallest yes that makes every future no harder to say.

means An initial small concession or opening gained now, used as a foothold to secure bigger agreements later.

from The phrase comes straight from the literal tactic of old-fashioned door-to-door salesmen: wedge your foot in the doorway before the homeowner can shut it, and you've bought yourself time to make the pitch. It's attested in English by the early 20th century and became a formal term in psychology — the 'foot-in-the-door technique' — describing how agreeing to a small request makes people far more likely to agree to a larger one later.
