Provenance

Where the line actually comes from

Credited to: Mary Kay Ash
Usual source given: None cited
Full form: “… You can go as far as your mind lets you.”
Status: Attributed — no primary source located

Don’t limit yourself. Many people limit themselves to what they think they can do. You can go as far as your mind lets you. What you believe, remember, you can achieve.

The popular short version is the first two sentences; the fuller four-sentence form is what circulates on most quote sites. No edition, page, or speech date accompanies it anywhere we found.

Goodreads: the full quote (community-added, unverified)

How we verified this

The line is credited to Mary Kay Ash on virtually every quote aggregator — Goodreads carries the full four-sentence form but flags that its quotes are “added by the Goodreads community and are not verified.”
No primary source is attached anywhere: none of the databases name a book, page, speech, or date, and searches of her books turned up no located passage.
Neither Quote Investigator nor Wikiquote has an investigated or sourced entry for this line — Wikiquote has no Mary Kay Ash page at all — so there is no specialist anchor to lean on.
No rival originator surfaced: nobody else is credited with the wording, and it is fully consistent with Ash’s documented “you can do it” message, which is why we treat it as attributed rather than disputed.

Because the exact wording can’t be tied to a specific dated work, we assert no copyright status. If it does come from one of Mary Kay Ash’s books (all published between 1981 and 1995), that work would be in copyright — but since no source is located, the honest classification is uncertain.

Fact-check

A caution, not a debunking

There is no sign this line belongs to anyone but Mary Kay Ash. The issue is thinner than a wrong name: the wording travels with zero sourcing, so “verified” would overstate what anyone can actually show.

Every quote database unsourced

Goodreads, BrainyQuote, A-Z Quotes and Quotefancy all attach the line to Ash with no book, page, speech, or date — and Goodreads warns its quotes are community-added and unverified.

Quote Investigator / Wikiquote no anchor

Neither has investigated or sourced this line; Wikiquote has no Mary Kay Ash page at all, so there is no authoritative confirmation to cite.

Best read as genuinely Mary Kay Ash in spirit and voice, but attributed, not verified — no one has yet pointed to the book, speech, or page where she first said it (Goodreads).

Context

Why it sounds like her

Mary Kay Ash built a company — and a management philosophy — around telling saleswomen they could achieve far more than they believed. Lines about refusing to limit yourself are the core of that message, which is exactly why this one sits comfortably under her name.

That fit is also the trap. A sentiment perfectly on-brand for a motivational figure is the easiest kind of quote to attach to them without evidence, and this line has spread for years on aggregator sites that copy each other rather than a documented source.

On-brand enough to sound certain — unsourced enough to stay honest about.
