I think that there is a lot of quite amazing ideas in the books of Rav Nahman of Breslov, but the fact that his name is associated with Breslov ruins the effect. Rav Nahman himself must have been aware of this problem when he wrote to his followers in Breslov in one of his five letters ''קצתי בישיבת ברסלב'' I have become disgusted with yeshivat breslov'' [or perhaps it could be translated ''I am disgusted with dwelling in breslov.] 

FOR his ideas really do not work well unless taken in a straight Litvak yeshiva atmosphere of straight Torah. but outside of that context, they tend to take people off into insane tangents. 

I found the approach to learning in Conversations of R.Nahman chap. 76 the most helpful, i.e., learning fast-- saying the words and going on. This helped a lot when I went to Polytechnic Institute of NY University.
