Most new traders spend their first year trying to predict the market better. Most experienced traders spend every year after that trying to react to it better. That shift in focus is usually the real turning point.
You don't need to be right about where the market is going to be profitable. You need a plan for what you do when you're right, and — more importantly — a plan for what you do when you're wrong. Traders who blow up accounts are rarely the ones who guessed wrong. They're the ones who had no rule for what happens next.
Discipline isn't about suppressing emotion. It's about deciding your rules in advance, when you're calm, so you're not making decisions live, when you're not.
This is why our programs spend as much time on trading psychology and rule-following as they do on charts. A great strategy followed inconsistently will lose to an average strategy followed with discipline, almost every time.
