In the way of learning of Rav Nachman of Uman there is an emphasis on finishing that book that you are doing. That is this way of learning involves two things. One is to say the words and go on [believing] that eventually you will understand even if you think than now you do not understand. The other is to finish that book that you are learning.  You see this in particular with Natan his disciple. When Rav Nathan first became close to Rav Nahman, Rav Nahman told him to go through the entire Shulchan Aruch in one year. 

[The Shulchan is the length of a medium sized encyclopedia. It was written by Rav Josef Karo, and the standard version includes commentaries, the Shach, Taz, Magan Avraham, and the Gra.]  

[I see this idea of how to learn as being something that if people would now about they would be helped in many ways. First of all, knowing Shas. Clearly the slow methodical way of learning in Litvak yeshivot is great for getting to deep understanding of a particular (sugia)/ subject. However it does leave one with a lack of general knowledge. So I think at least some amount of time in learning ought to be דרך גירסא just saying the words and going on Also, this method of learning applies to Physics and Mathematics. And learning Physics is Math is important as we see in the Rambam in the Guide abd also in the Yad HaChazaaka in a amore hidden way.
