Rav Nahman says [Le.M I;129] to honor the festivals and/or to be close to a true tzadik helps to rid oneself of pride. The question that I have here is that there is no indication of any method to be able to discern who is a true tadik- as opposed to who is a phony. But I do have a suggestion. In the Le.M  vol II Rav Nahman says to be in a Litvak yeshiva is the same essence as being with a tzadik.
