where does fake it til you make it come from
Fake it till you make it The phrase "fake it till you make it" is similar in meaning to the idiom "act as if", and is also similar to Aristotle's idea that to be virtuous, one must act as a virtuous person would act.
The real McCoy The phrase "The real McCoy" may be a corruption of the Scots "The real MacKay", first recorded in 1856 as: "A drappie o' the real MacKay", ("a drop of the real MacKay"). This appeared in a poem Deil's Hallowe'en published in Glasgow and is widely accepted as the phrase's origin.[1][2][3][4]
