Trading until the end, it's not really about chart-reading skills or understanding the charts, but about that heart.

Having capital is the only way to have the next opportunity. Without capital, no matter how good the market conditions are, they won't matter to you. So the first iron rule is: only use idle funds. This is not motivational talk; it's the bottom line of survival.

Don't touch unfamiliar assets, really. The phrase "this time is different" has tripped up many people enough to form a line. Holding on stubbornly isn't faith; it's slow self-destruction. Stop-loss isn't about giving up; it's about leaving yourself a way out.

Go against human nature to live longer. When everyone is frantically buying, you need to stay sober; when everyone is selling off, that's actually the time to pick up bargains. The real danger is never short-term losses, but thinking you've "awakened" after making a little profit.

The market is like a magnifying glass, amplifying everyone's greed and fear infinitely. You need to learn to ride the waves, not be eaten by them. Many retail investors keep cycling through this loop: they can't hold during rises, and they stubbornly hold during drops, ending up repeatedly harvested.

Ask yourself three questions: Do I really understand? Who am I? How much am I willing to lose? In this circle, emotions and chips often weigh more than fundamentals.

Be picky when buying, be patient with holdings, and be decisive when selling. You're not trying to beat the market; you're trying to control your own hands. One last truth: those who have avoided countless crashes often die in the obsession of "bottom-fishing" at some point.
