When you can truly make a living from trading, that state is not excitement but calmness. You are no longer in a hurry to prove anything, nor will you be led by the market. You know what you are doing, when to take action, and when to wait. You no longer fantasize about 'getting rich quick,' nor do you chase after 'one trade to greatness,' but instead, like an old farmer, you sow, wait, and harvest, all in rhythm.
Stable profits are not just about making money from a few trades, but about enduring market downturns and consecutive losses while still being able to withstand pressure and execute your plan. You can see the slowly growing curve in your account, and you will no longer be emotionally affected by the daily fluctuations. The real ability of those who can make a living from trading is not making money, but being able to withstand losses and continue trading with a calm mind.
Moreover, it's particularly realistic that you must ensure your account's profits are not due to luck but are based on a stable method. You are not relying on gambling or feelings, but on strategy and rules to step by step achieve success. So you will feel very certain that no matter how much the market fluctuates, you can survive.
Most importantly, you no longer fantasize about trading bringing you a 'free life.' You are clear that this line of work is actually very tough and lonely, but you have grown accustomed to it and are willing to continue. You know this is not a shortcut but a path you truly acknowledge.
When you no longer fantasize about trading, and only have cognition and execution left, this is the sign that you can rely on it for a living.
