Imagination and "what ifs" always bring a sense of delight.
In his previous life, many people around Xu Yuan enjoyed this.
Imagining what it would be like to correct the mistakes on an exam, imagining what it would be like to seize the squandered opportunities during a startup, imagining what it would have been like to make different choices in the naive years of budding romance and end up with different results.
Whenever he heard his friends express such sentiments, Xu Yuan always felt like laughing.
Although fantasizing "what if" brings a fleeting high, constant fantasizing brings a constant high—but it can only remain as fantasy.
This life of theirs is basically settled.
If you fail an exam, just do better on the next one.
If a romance is unfulfilled, perhaps the next will be with someone even prettier.
Rather than savoring the fleeting joy brought by this mental opium, it's better to focus more attention on the future.
