Just saw this photo and couldn’t help but感叹 the unpredictability of life. A 985 graduate, passed the civil service exam, landed the job—so many people envy it, yet it all comes to an abrupt end. Who would have thought that while sitting in a towering customs office building, you could still be swallowed by a mudslide.

On the road of life, there are many risks and many forks. Choice matters more than effort; one wrong step can cost you your whole life.

It’s impossible to always choose correctly, but at the very least, you should do your best to guard against risks, and work hard to keep yourself from standing too close to the edge of danger. Because some mistakes, once made, are hard to correct—or you may never get another chance to correct them. For example, marriage. For example, life and death.

Especially when everything seems smooth and effortless, a seemingly insignificant mistake can wipe out all your past achievements. That’s what the old saying calls “capsizing in the gutter.”

I once had a friend. He was born into a well-off family, smart and handsome, with outstanding talent. Like Brother Sun, he also got into Peking University. After completing his master’s degree, he smoothly entered a certain bureau in Beijing. The director took one look at him and kept him close, having him serve as a secretary—training him as part of the succession pipeline. His future looked bright.

One day, he had a toothache. Instead of going to the hospital to save time, he got a tooth filled at a nearby private clinic. About a month later, he started feeling weak all over, and his urine turned the color of strong tea. When he got checked, he found out he had hepatitis B. He was hospitalized and treated. After he recovered and returned to work at the bureau, he discovered that his desk and chair had already been moved away from the director’s side and placed far, far distant. From then on, his career path was over. Not long after, he resigned quietly and became a lawyer. Just by getting one tooth treated, his life took a dramatic turn.

Trading is the same as life. And especially when things go smoothly, that’s often when you’re closest to blowing your account. At 37, Roger—financially free—passed the “life hack” to his daughter: “No matter when it is, if you feel like you’re all-powerful, stop. Don’t do anything.” $SOL
