I think however the only advice is that one should do his best to go out and get the basic books of Torah and to learn them on his own. That is the Old Testament, The Babylonian Talmud, the poskim--that is the Rambam, Tur, and the Shulchan Aruch of Joseph Karo, the basic commentaries Rabbi Akiva Eiger, Rav Chaim Soloveitchik [Chidushei HaRambam], and the writings of Isaac Luria. Do this in your own home so you are not dependent on others to have a place to learn Torah.
And there is something to be gained from this endeavor. He who accepts on himself the yoke of Torah from heave there is removed from him the yoke of the government and the yoke of making a living.
And if anyone needs to learn Torah it is certainly not just frum(Orthodox) people. Everyone needs to learn Torah because everyone needs to become free from the government and free of drudgery. I have never hear of a person who enjoys waiting in line at government agencies or enjoys interaction with any government, or enjoys having his time wasted on drudgery. Why not take the words of the sages at face value and start to learn Torah today?
But clearly not everyone is fit to learn Torah. There are obstacles that are placed in front of people to keep them from this great gift. There are questions in philosophy which make even the existence of a law given by the First Cause impossible. That is metaphysics has had a good number of of people that thought it is impossible. And then there are questions in one's own mind? I can't account for all the questions but I think a good deal of them have to do with abuse of Torah. And there are lots of variations of that. Like, "If Torah is so great why is so and so a jerk?" Or "If Torah is so great why did so and so suffer." These are all good questions. The last was asked by Job and God told him that his questions were good questions and that his friends that claimed he was suffering because of sin were in fact wrong. And in fact we know from the very beginning of the book that he was suffering in spite of his being righteous. So by analogy to the first question it is possible to say it also is a valid question. But in spite of this it is expected of us to do our best to discover Gods will for our lives and to fulfill it. That fact that others do not succeed to not mean we should follow their example.
This does not mean not to go to university. The Vilna Geon clearly himself wrote book on Trigonometry and told one of his students to translate all of Euclid into Hebrew and to publish it. Not does this mean not to work for a living. It only means that when one is not working or doing university he should learn Torah in every day in this way. To have one session in the Old Testament in Hebrew. He should start from the beginning and have place marker in the book and just say the words in order. If one does not understand Hebrew then he should learn it with an English translation along side of it. Don't do any commentaries because then you will never finish it. You need to get to the end. Then the second time you can add commentaries if you want. Then you need to have a separate session with the Gemara. Start from Brachot and say page after page until you have finished Shas at least once. And the same goes for the Rambam and the Tur and the writings of Isaac Luria.
I should mention that none of the above requires one to accept any particular set of beliefs. All one is required according to Rabbi Joseph Albo is rather common sense propositions. That things had a beginning and so needed something to begin them- a first cause you could call it. And that there was only one first cause. Not two or more. Its seems straightforward enough. It is hard to know what kind on alternative reality people need to believe in in order to deny either of these simple propositions.
