From you
Fear, greed, anxiety, stress, and boredom are all your real enemies.
Any strong strategy in the world can collapse if your mind is not balanced.
Remember
If you enter a trade while you're not calm, you'll lose even if your analysis is correct.
The market favors the patient, not the anxious.
Skill is not in knowing everything.
Skill is in applying what you know calmly.
The rule is to control your emotions and manage your account.
