Prediction can sometimes favor you or fail you, because trading is also a game of luck and there's no one person that is perfect in prediction, just that when you are favored, it looks like you're the champion but I tell you that no champions forever.
In trading, failure is indeed a problem we can never avoid, but how can that failure become a catalyst for change after so many failures? Of course, it's not as easy as it seems because talking about failure in trading plays a psychological role, especially when talking about the amount of money we've lost. But this is where emotional control lies for someone who wants to achieve success in trading, because every failure must be a prerequisite for achieving success. I disagree with saying trading is a game of luck, because it requires knowledge to get started, and talking about luck is akin to gambling. In context, you won't always profit in trading, but how to maintain opportunities to continue in a situation that is not detrimental even though you also lose occasionally.
