Instead of taking one big trade with conviction and accepting the outcome (win or lose) and walking away after that, many traders prefer to die by a thousand paper cuts. They prefer opening one small trade, when they lose they enter again, and again and again and again. In the end their loss becomes bigger than it would have been if they just took one big trade and allowed it to play out. I call this death by a thousand paper cuts because the small losses add up and become a large loss.
