TraderFeed: Trading Addiction: The Side of Trading That Few People Discuss:
"Take the trader who loses money in a downward spiral through the day, without ever taking a break or exercising restraint. How is that different from someone who drinks themselves into a coma or who gambles away the family paycheck? The circular dynamics are identical: out of control behavior, unwanted and negative consequences, remorse and guilt, efforts at control, eventual relapse and loss of control."
