When I am trapped in stocks but refuse to sell,

I finally understand,
Why some people are badly hurt in love but still refuse to let go.
After I sell all my holdings, I still can't help but repeatedly check their rise and fall,
I finally understand,
Why some people keep spying on their ex's life even after breaking up.
When I just sold, it soared all the way up,
I finally understand,
Why some people can't stand seeing their ex doing well after a breakup.
When I heavily invest in a stock, my emotions are completely driven by its fluctuations,
I finally understand,
Why it's said that love shouldn't be too full, excess will turn into reverse.
When I like a stock but haven't bought it yet, it suddenly skyrockets,
I finally understand,
Why some people regret missing their white moonlight for a lifetime.
It turns out the stock market and human hearts follow the same principle:
Reluctance, inability to let go, unwillingness, fear of losing, regret over the past.
