what's a bas yisroel to do?

I started reading(one of) Rav Lichtenstein's recent book(s) over the weekend. This is probably one of those books I will never finish, so I'm just going to write down my thoughts so far and hope someone can set me straight... also, i don't have it in front of me, so the citations will b fuzzy.

1- in ch. 1 he talked about the "natural order," the one that we have some sort of generic obligation to uphold since creation under "leovdah uleshomrah." at least once Rav Lichtenstein refers to its "social" aspects as well - but there are no examples! so what is the "natural" social order?

2- the whole calculus of learning vs. worldly professions, making money, etc, has two basic soures for why one should seek to maximize "direct" spiritual activities, especially Torah, despite the values of "binyan yishuvo shel olam."

(a) the world stands on Torah, avodah, and gemilut hasadim. So one should seek to be involved in these directly as much as possible. Rav Lichtenstein does suggest, however, that many professions may fall under the category of gemilut hasadim because of their effect in "repairing the world" (on a side note, i found it interesting that here he seems to have carefully avoided the contemporary non-orthodox fad of harping on tikkun olam as a central, independent value, instead subsuming it under chessed.)

(b) the obligation to study torah yomam va-laylah - basically, as much a possible ("kefi kocho," acc. to Ramban or some such rishon, i think).

all together, acc. to Rav L, this means that one should choose a profession that allows time for avodah and torah study - one should seek to be a "ben torah."

but what about those of us for whom only (a) applies?

should we also seek to be bnot torah as some sort of middat chassidut, or should we davka focus on binyan yishuvo shel olam as gemilut chasadim because men are discouraged from doing so? or are we totally unadressed here, and really our role in sustaining the world is the gemilut chasadim of the home?

i realize that rav Aharon is a rosh yeshiva for boys, and he's talking to them, but, if you will permit me a moment of melodrama, who's talking to women of similar intellctual/social persuasions* even half as seriously?!?

Some women seem to simply adopt the male model of ben torah and try to do it as girls. that's not nec. bad, but i think there has to be something else, too...

*not that i'm claiming a pervasive intellectual or emotional affinity with The Gush, but I think someone speaking to that audience would have more to say to the specific situation f someone like me than, say, Rebbetzin Heller.
