英文諺語 Every dog has its day
Every dog has its day 十年風水輪流轉（狗也有走運的一天）
This phrase is recorded as being first uttered by no less a notable as Queen Elizabeth I. As Princess Elizabeth, in a letter to her brother and in response to his request for a picture of her, she wrote:
Notwithstanding, as a dog hath a day, so may I perchance have time to declare it in deeds.
The letter was published by John Strype in Ecclesiastical Memorials, 1550. It appears that Elizabeth was merely quoting what was in her day already a well-known proverb, although no record of it has been found that predates her writing it down.
