Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.

No Einstein source has been located. Quote Investigator traces this wording, already attributed to Einstein, to Matthew Kelly’s The Rhythm of Life (Fireside, 2004), p. 80; that book was not inspected here. It also documents an older animal-school allegory, credited to Amos E. Dolbear, that illustrates the same educational idea without this sentence; the connection is conceptual, not an established transmission of the modern wording. CORRECTIV independently reports searching The Ultimate Quotable Einstein and finding no reference to this saying. This run checked those two investigations and Wikiquote, not Einstein’s complete writings; the local atlas holds no Einstein source texts. The author of the modern wording and any appearance before the 2004 edition remain unestablished.

An educational encouragement circulated under Einstein’s name. In the earliest close wording located by Quote Investigator, Matthew Kelly’s 2004 edition of The Rhythm of Life introduces it as Einstein’s without identifying a letter, interview or other Einstein source.

A single test can mistake a person’s unsuitable skill for their overall ability and damage their confidence.

It is not an authenticated pronouncement by Einstein about education. Matthew Kelly is a documented transmitter of the attribution, not an established author of the saying.
