Life seems to last for decades, but the key moments are just a few.

Every day may seem similar, but at a special moment, if you seize the opportunity and make the right move, your life trajectory can be completely different.

For example, in the senior year of high school, those who grit their teeth and give it their all might transition from ordinary to outstanding, from limitations to a larger stage.

That moment is the 'key K-line' of life.

Trading is the same. Opportunities arise every day, and there are many profitable segments, but the ones that truly change your account are always those few critical trades.

Identifying key points, managing your positions well, and executing that one trade is more important than trading a hundred times every day.

It's not about trading hard to make money, but rather whether you can capture a few key positions and deliver the most beautiful strike.

This is the essence of trading, and it is also the underlying logic of life.
