There is no such thing as absolute in this world.
For instance, the relationship between fortune and misfortune.
The ancients once used the phrase 'Good luck lies in misfortune, and misfortune hides beneath good luck' to succinctly summarize the relationship - who can determine its extremity? There's no absolute. That which is regular turns extraordinary, and that which is benign, eerie. The confusion of mankind persists as long as the days are.
Another example is the difference between the brave and the cowardly.
People who dare to confront dark and desolate life and face a stream of blood are called the fearless. Also, those who do not dare to confront such life yet still manage to force themselves to face that blood, are also known as the fearless.
This world never refrains from playing terribly malicious pranks on you.
