From the Book of Rites, which apparently paraphrases the Classic of Changes:

《易》曰：「君子慎始，差若豪氂，繆以千里。」此之謂也。 [Classical Chinese, trad.]
《易》曰：「君子慎始，差若豪牦，缪以千里。」此之谓也。 [Classical Chinese, simp.]
From: The Book of Rites, c. 4^th – 2^nd century BCE, translated based on James Legge's version
“Yì” yuē: “Jūnzǐ shèn shǐ, chā ruò háolí, miù yǐ qiānlǐ.” Cǐ zhī wèi yě. [Pinyin]
This sentiment is found in the words of the Yi, ‘The superior man is careful at the commencement; a mistake, then, of a hair's breadth, will lead to an error of a thousand li.’
