I don't know. They might've just chosen a bad example. But it seems quite unconvincing since it's using the exact same example that is already used by the willpower-exists way of thinking. Summary usually goes like this: Since willpower is limited, try to reduce the stress and don't beat yourself up about failures, because that would exaust the willpower you need to succeed.
