The original sentence of this sentence comes from Shakespeare's play "The Tempest". The original sentence "Everything in the past is a prologue."

Everything in the past is a prologue. Love everyone, trust a few, and trust no one. I wasted time, and time wasted me. In the gloomy days, we should not let the cold fate rejoice; since fate comes to insult us, we should retaliate with a calm attitude. Wise people never sit down and lament over failure, they must be optimistic and look for ways to save it. "Everything in the past is a prologue." It means that everything that has happened is in the past.

The passage of time can easily throw people away. "All the past is just a prologue" reveals another outlook on life: what has happened, whether lost or gained, is in the past. Stop dwelling on the past, seize the present, and face the future.
