Check your machine before you drive it, and stay alert. Freight trains do come roaring across unmarked crossings. The market is a mechanism for transferring wealth. It does so by causing pain. Great wealth transfers in times of great pain.
Losses are a way of causing pain.
Card sharks operate by letting the sucker win big in the early going. But by the end of the game, the card sharks have all the sucker's money, his clothes, his house, and the sucker's gratitude for letting him get away from the table with his life. If you're making bigger and bigger trades, think about the sucker who ended up betting it all exactly at the time the sharks held all the winning cards. Trading is a business. You go to work in the morning, go home at night, and earn a paycheck at the end of the week.
