[My basic story was my first year in Shar Yashuv was fraught with difficulty. But the second years I started getting more into the learning. That is pretty much when I was what you might call addicted to Torah. I had to get my "Torah high". If that sounds like a drug addict, well maybe it was. After all Aristotle said that "virtue is habit."
That is, you have to choose as to what kind of habits you want to get yourself accustomed to. I made a choice to get into the Torah addiction instead of other kinds of things which I might have chosen.
Later on, the Mir in NY was my second destination. And then Israel. The second I got off the plane in Israel, that "spirit Torah" came in a more intense way.
Nowadays, I would say that the Litvak yeshivas [that go by the Gra and Rav Shach] are the citadels of Torah, though I myself am far off from them. Probably the best is Ponovitch. Also the yeshivas based on the Gra (founded by the father of Rav Eliyahu Silverman) in Jerusalem are great.
[But as I have said before, nowadays I would go with the idea of many Rishonim that learning Physics and Metaphysics ought to be supplementary to the basic structure of learning Torah.]
If one would want to improve the situation, I would recommend that the Litvak yeshivas should go with the Gra totally since after all, it is that path of the Gra that endows them with the spirit of Torah in the first place.
