In this case it's more about where you get the knowledge. To parallel the motherhood example FTA:
> She does what she does not because she is going to be paid for her services and not because she is the most highly skilled, but because she wants to do it. And she does “the things worth doing,” which are the things closest and most sacred to all of humanity – nurturing a baby, teaching a child the first things, and, in fact, all things.
You're not doing the exercises that are being chosen by the expert who is telling you what to do because you're paying them, you're doing the exercises you want to do purely out of self-interest.
