We often feel a sense of regret in many situations. When we were young, we felt regret after being broken up with someone we loved very much; we felt regret when we worked hard on something and were schemed against; we felt regret for not accomplishing something valuable in our lifetime.

Many people also lost their lives when they were young, some to defend their country, some due to serious illnesses, and others because of accidents, etc. They too experienced a lot of regret, feeling that there were many things they didn't have the chance to do.

In fact, the greatest fortune is when you realize your regrets, you are still alive and have the opportunity to become a better version of yourself. No matter how you choose in life, there will always be regrets, and these regrets may very well last a lifetime.
