I had a intense love of Torah and hoped to spend my life learning Torah. But I can see that  there is such a thing as השגחה פרטית (Divine Providence) that sometimes can create a situation where what might be right, but that there is some deep reason why things have to work out in a different way. So while surely learning Torah is the greatest of all mitzvot as it states clearly in the Mishna in Peah (and made even more clear by the Yerushalmi that every word of Torah is worth more than all the other miztvot,) still there is plenty I needed to learn by being flung out. One invaluable lesson I learned was that the Litvak yeshivot, have no idea of why the Gra is important. They walk in that path (to some degree), but really have no concept of "Why?" I learned that the herem (excommunication) that the Gra signed is much more significant and relevant than anyone today can even begin to imagine.

["Herem" as understood as excommunication is not an exact translation. It means not to have anything to do with one under the herem at all. Not even to sit within four yards of that person. Much less to learn Torah from them.]

But by being in my personal exile, I learned at lot more. But not everything is applicable to everyone in the same way as that first lesson. For example, I learned the importance of the opinion of Ibn Pakuda [of the Obligations of the Hearts] and the Rambam about the importance of learning Physics and Metaphysics. But I realize that the Ramban [Nahmanides] must have disagreed with this at least in terms of the Metaphysics part.] 

Though not at all talented in Mathematics and Physics, I did gain some understanding by means of the idea of the Musar book אורחות צדיקים [Ways of the Just] where in the part about learning Torah, he goes into the idea of "Girsa" saying the words and going on. I used that idea of just saying the words and going on for Mathematics and Physics. That does not make me smarter, but it does help me understand a lot more than if I would say, "I am not genius, so why should I try?"
