Successful Trading is the Capacity to Take Pain.
To be a great trader, you have to have the capacity to take large amounts of stress and pain - frequently and repeatedly. You must get used to the pain, or feel the pain incessantly but continue to execute in the opposite reaction of human beings. When things go your way, be optimistic and manage risk. Most of the time, it won't go your way but you still dream optimistically. When they don't go your way, be extremely fearful that it will continue to not go your way.
Yet still look for the next trade. One of those trades where you keep risk minimal, but keep adding to your position WILL play out.
Happy hunting and losing. Lose Responsibly and Joyfully.
