It's like a nurse looking after an ill patient. Which is the better nurse? The one who smothers the patient with sympathy and says ‘never mind, dear, there there, you just lie back and I'll bring you all your meals. I'll bring you all your papers. Just lie back, I'll look after you'? Or the nurse who says ‘Now, come on. Shake out of it. I know you've had an operation yesterday. It's time you put your feet to the ground and took a few steps. That's right, dear, that's right. Now get back and take a few more tomorrow'...Which is the one most likely to get results? The one who says, come on you can do it. That's me.
