I remember a line in Seanan McGuire's Every Heart a Doorway to the tune of Nancy—who, it was earlier established, had put in some thousands of hours practicing how to stand perfectly still—being really strong, precisely because of that unexciting form of exercise. That something like what you're talking about?

I mean, I keep telling people "I need patience. Is there an instantaneous way to get me some?" :P but like. I really do need patience...

Thanks.
