“How can I drop the anti-rational part of my mind that interferes with me taking my children seriously?”
When you struggle against or take a coercive approach with another person, the natural response of that person is to defend their corner and fight back. The same happens inside our own minds. When you are fighting a part of your own mind, that causes the part you are trying to stamp out to dig in, to entrench itself, to defend its corner more vigorously.
