Explains traders' behavioral changes when trading money needed for bills, not a discipline problem.

You're going to hold on to a loser well past your stop loss because you can't afford to lose that money today. Now these are behaviors that you know you're supposed to avoid, right? And it's not because you're undisciplined. It's because your nervous system needs this month's trades to pay this month's bills. And it's really hard when the math and the system you're running tells you you're going to be waiting a lot. You're going to be sitting on your hands. You're going to be taking losses because that is part of the process. It's part of your edge. One single trade does not determine the success of your strategy. But when that one single trade is required to pay your rent all of a sudden it feels a lot more important.
