“How willingly we will put up with unpleasantness if commanded to by the magic words ‘doctor’s orders.’ The doctors says you’ve got to take this nasty medicine, and you’ll do it. The doctor tells you you have to start sleeping hanging upside down like a bat. You’ll feel silly, but soon enough you’ll get to dangling because you think it will make you better. On the other hand, when it comes to external events, we fight like hell if anything happens contrary to our plans. But what if a doctor had prescribed this exact thing as part of our treatment? What if this was as good for us as medicine?”

Ryan Holiday, The Daily Stoic (Page 328)
