When you can really 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, know when to act, and when to wait. You no longer fantasize about 'getting rich quickly', nor do you chase after 'making a fortune in one trade', but instead, like an old farmer, you plant, wait, and harvest, all in rhythm.
Stable profit is not just about making money from a few trades, but about enduring market downturns, consecutive losses, and still being able to withstand pressure to execute the plan. You can see the slowly growing curve in your account and will not be swayed by the ups and downs of a single day. The real ability of those who can make a living from trading is not making money, but being able to endure losses and continue trading with a calm mind.
Another very realistic point is that you must ensure that your account's profits are not based on luck, but on a stable method. You do not rely on gambling, nor on feelings, but on strategy and rules, step by step. So you will be very certain in your heart, no matter how much the market fluctuates, you can survive.
Most importantly, you no longer fantasize about how much 'freedom' trading will bring you. You are clear that this industry is actually very hard and lonely, but you have already gotten used to it and are willing to continue. You know this is not a shortcut, but a path you truly recognize.
When you no longer fantasize about trading, and only have cognition and execution left, this is the sign that you can make a living from it!
