This sentence comes from Shakespeare's play The Tempest. The original text: "The past is the prelude." "Past as Smoke" appeared in the first scene of the second act of "The Tempest", from the mouth of my younger brother Antonio. In the translation of the play, this sentence is also translated as "everything in the past is just an introduction" or "everything in the past is just a prelude".
Extended data:
This sentence is most suitable for anyone, and it is not abrupt in any scene. No matter how well you get along in the workplace and whether your personal development is smooth or not, as long as you haven't retired, the scene won't end. Life is too short to try again, and you are not afraid to start from scratch again and again. But as long as you are ambitious, willing to work hard, persistent and hard-working, you will certainly achieve extraordinary achievements and reach a height that seems unattainable at first.
