Even though there is great advice and deep ideas in the book of Rav Nachman of Breslov, there is to be a lack of appreciation of the importance of the Gra. For after all where do you find people really sitting and learning Torah day and night for its own sake except in a Litvak yeshiva that is connected with the path of the GraThis is so obvious that it barely needs mentioning. But still since  not everyone is in the vicinity f a authentic Litvak Yeshiva, for those who have not seen or felt the power and light found in the authentic world of Torah of the Litvak yehivot, for them this is worth mentioning.
