His most ideal life was to spend the first 20 years step by step, earn money from various sources in the middle 10 years and live the most extravagant life at the moment. He just spent the last money on his 40th birthday and died empty-handed. He feels that people always have regrets, and they will never become less and less with the passage of time. Why not end this life happily before regretting more and when the current situation is relatively satisfied. But that person wants to stay together forever and wants to grow old.
