No dialogue, letter or fragment of Plato has ever been produced for this line. Wikiquote files it under Disputed on its Plato page, recording that the “Alleged source in Plato unknown” and that the earliest occurrence anyone has located is a Tweet from 2011 — more than two thousand years after Plato died. It reads as a modern motivational slogan, and it also circulates with no author credited at all — an IFB “Daily Inspiration” post of 8 May 2013 runs it that way.
“Successful people never worry about what others are doing” the attribution to Plato is unverified. No dialogue, letter or fragment of Plato has ever been produced for it. Wikiquote lists the line under Disputed on its Plato page, noting that the alleged source in Plato is unknown and that the earliest occurrence located is a tweet from 2011. Via Quotle.info

In context
Evoking the themes of success, purpose and character. Theme: "Successful people never worry about what others are doing". Atmospheric and restrained, cinematic directional light, a muted period-appropriate palette, fine grain and texture. Compose with generous empty space for the quote and a small credit line. No lettering in the image itself.
Minimalist
Minimalist editorial slide for the quote "Successful people never worry about what others are doing". Clean background, a single muted accent color, generous negative space, subtle paper or linen texture, no literal illustration — let the words carry it. Reserve clear space for a serif quote and a small credit line. No lettering in the image itself.

Successful people never worry about what others are doing.
No source text
There is no fuller context to quote. The line has never been traced to a dialogue, a letter or a fragment, so no surrounding passage exists. In wide circulation it has instead grown a second clause — “…because they’re too busy working hard to achieve their own goals” — which is equally unsourced and does not appear in Wikiquote’s entry.
Wikiquote’s Plato page ↗ lists the sentence under Disputed, with the whole of its documentation being: “Alleged source in Plato unknown. Earliest occurrence to have been located is a Tweet from 2011.” That 2011 posting is the furthest back any researcher has been able to push it. Wikiquote links the post itself — @ochocinco, 2011 ↗ — but we could not retrieve it, so whether that tweet itself credited Plato is unconfirmed.
Quote Investigator has run down a long list of Plato attributions ↗ — the “hour of play” line, “Be kind; everyone you meet is fighting a hard battle,” the “democracy is the worst form of government” line — but has never published on this one, and a site search for the wording returns nothing.
No rights status can be asserted, because the wording cannot be tied to any work. Plato’s Greek has of course been in the public domain for centuries, but that is beside the point here — this sentence is not his, and no identifiable modern author has been documented for it either. Separately, on the modern English used for context: the Republic passage quoted below is Paul Shorey’s translation, first published as Plato in Twelve Volumes, Vol. 5 (Republic Books I–V; Cambridge, MA: Harvard University Press; London: William Heinemann Ltd., 1930). Its US copyright expired on 1 January 2026, so that volume is now public domain in the United States, and Shorey died in 1934, so it has been public domain in life-plus-70 countries since 2005. Shorey’s companion Vol. 6 (Republic Books VI–X, 1935) stays under US copyright until 1 January 2031. The “1969” carried in the Perseus citation is a later Loeb printing, not the translation’s first publication and not a copyright date.

Fact-check
Who gets the credit — and why none of it holds
This sentence is usually pinned on Plato, and it also circulates with no author credited at all — an IFB “Daily Inspiration” post of 8 May 2013 runs it that way. That instability is itself the tell: a line with a real source keeps its author.
✕
The dominant credit, on graphics, cards and merchandisePlato Unsourced
No dialogue, letter or fragment is ever named. Wikiquote files it under Disputed on its Plato page ↗ with the note that the “Alleged source in Plato unknown.” The wording is modern motivational English, and nothing in the searchable English corpus of the dialogues corresponds to it.
✕
How it also circulates, often with no name at all“Anonymous” / “Unknown” / no credit Uncredited
An IFB “Daily Inspiration” post of 8 May 2013 ↗ runs the line as a standalone motivational quote with no author credited whatsoever. Elsewhere it is tagged simply “Anonymous” or “Unknown” — which is closer to the truth than the Plato credit is.
✓Nobody has produced a Plato text for it. Wikiquote’s Plato page ↗ records only that the alleged source in Plato is unknown, and that the earliest occurrence to have been located is a Tweet from 2011 — more than two thousand years after Plato’s death.
Context
The Platonic idea that actually exists — and isn't this
The line has the shape of an aphorism and none of the provenance of one. It names no dialogue, no book, no translator; it simply appears, fully formed, on inspirational graphics, Pinterest boards, greeting cards and stock-photo templates with “— Plato” underneath. When a saying can be traced no further back than a social-media post, the ancient name attached to it is decoration rather than citation.
What makes the misfire interesting is that Plato does have a famous line about minding your own business — and it means something almost opposite. In Republic Book IV, Socrates arrives at the definition of justice by recalling “that each one man must perform one social service in the state for which his nature is best adapted,” and then that “to do one’s own business and not to be a busybody is justice” ↗ (Paul Shorey’s translation, Perseus Digital Library). That is a claim about civic role and the ordering of a city and a soul — not advice about ignoring your competitors on the way to personal success.
Plato’s “mind your own business” is a theory of justice, not a productivity tip.
How the wording drifts in circulation
In the most widely shared social-media version the line has grown a second clause — “…because they’re too busy working hard to achieve their own goals” — which is itself unsourced and does not appear in Wikiquote’s entry. Neither half has ever been tied to a text.
The attribution is unstable too. The same sentence circulates credited to Plato, credited to nobody, and labelled “Anonymous” or “Unknown.” A saying that drifts this freely between a famous name and no name at all is a strong signal that it has no author of record.

c. 428–347 BC · Athenian philosopher, founder of the Academy
Plato was an Athenian philosopher, a student of Socrates and the teacher of Aristotle, who founded the Academy in Athens around 383 BC and is widely treated as the foundational thinker of the Western philosophical tradition. His surviving work is almost entirely in dialogue form — the Republic, Symposium, Phaedo, Timaeus, Laws and others — in which Socrates usually leads the argument and Plato never speaks in his own voice. That combination of enormous name recognition and a corpus almost nobody reads makes him one of the internet’s most reliable magnets for invented quotations: Wikiquote’s Plato page carries a long list of misattributed and disputed lines alongside the genuine ones.
