p. 83 The mistake of only learning with pilpulim (complex analysis) and iyun (depth). Our learning must translate into practical results and "bear fruit." However, merely learning mussar (ethics) and chassidus is also not enough. We must study those areas in Halachah (Jewish law) that apply to our daily life (e.g., Shabbos, kashrus) and work on our neshomoh (soul) with mussar and chassidus at the same time. Preparing for a Yom Tov (festival) by studying the halachos of that Yom Tov. Mitzvos on auto-pilot without understanding the halachos. Taking minhaggim (customs) and ignorance to extremes. The same davening (praying) and learning for 50 years, and nothing has changed!
