Interesting fact

The origin of the phrase ‘third time’s a charm’ is probably ancient, as things that come in sets of three have often been associated with good luck due to their similarity with the Holy Trinity of Christianity. The first time a similar phrase was seen in print was in 1839, in Elizabeth Barrett Browning’s work Letters Addressed to R.H. Horne: “The luck of the third adventure is proverbial.”
