Ike: When i think about directives, is they're great if you can get them from other people. But they're different, again, going back to this imitation verses, like knowing and understanding. You're doing the mental work of reflecting, integrating staing, and then you're coming up with these directives. And we haven't done the work in space repetition, like unkey as for us, flash cards. I don't want to read a 400 page book about nutrition and diet. That's an example where i just want somebody to tell me what to do.
