All the past is a preface. Love everyone, trust a few, and live up to no one. I wasted time, and time wasted me. In the gloomy days, don't let the cold fate secretly rejoice; Since fate has insulted us, we should take revenge calmly. Smart people will never sit down and lament for failure. They must look optimistically for ways to save failure.

The past is a preface, which means that as long as what happened, it is a thing of the past. Philosophy is to stop thinking about the past, whether it is good or bad, but to face the future calmly. Everything that happened has become a thing of the past. I am not afraid of the future and don't think about the past. "Everything in the past is a preface" is a sentence of Shakespeare. This sentence comes from Shakespeare's play The Tempest, and it has also been translated as "all the past is just a prelude" or "all the past is just a prelude".
