Stock trading is the most difficult profession to succeed in the world, but also the most profitable. Trading is like drinking water; if there are three thousand streams, taking just one sip is enough. Your rules have long defined "your cup": when the market conditions match the system signals, act decisively without hesitation or delay; once the trend falls short of expectations, cut losses and exit immediately, without fighting or hoping. You must clearly understand that the market always has endless money to make; your system can only capture limited opportunities. Making the profit you should and can make is already a victory. Market trends that do not belong to you, no matter how crazy the rise or how fierce the fall, are irrelevant to you. True trading experts understand "knowing what to do and what not to do." They use filtering systems to block temptations, recognition systems to focus on core opportunities, and firm execution to combat the human weakness of "fear of missing out." Patience is not passive waiting but active screening. Sticking to rules is not stubbornness but respect for the market. When you learn to give up 99% of ineffective opportunities and focus on that 1% of exclusive trends, profits will naturally follow. Every day in the market, there seem to be many trading opportunities; seeing others make money makes you eager to join, but the key is not how many trades you seize, but whether you seize the limited opportunities within your system. Don't expect to win big and small at once—that's the most foolish mindset. Opportunities outside your system do not belong to you.
