What goes inside the Mind of a trader is directly related to the success or failure of a trader. Charts matter, Edge matters , Timing matters , Understanding your market matters.... but the commonly under estimated thing in my opinion is "Frame of mind" as they say:
Watch your thoughts; they become words. Watch your words; they become actions. Watch your actions; they become habit. Watch your habits; they become character. Watch your character it becomes your destiny." Lao Tzu

As a trader we need to be mindful of our mental state and if we don't feel 100% in the correct state of mind, we should walk away from the trade.
