I used to think taking profits was just a skill. Now I realize that taking profits is actually a form of self-control. My cousin has made money on countless trades, but in the end, she lost to the thought of "just one more try." When profits are floating, I always feel I can earn a little more. But what I get is not more gains, but a profit retreat. Eventually, from being profitable, it turns into a loss. I once heard a saying: I never go broke by selling too early. I don't know why, but in memes, I just understand the importance of knowing when to take profits.
