Harav Shlomo Wolbe ztl wrote the volume of Alei Shur in 1966. The sefer contains his mussar analysis on a proper regimented life of a yeshiva student. The second volume of the sefer was published about 20 years after the first and was an intense glimpse into his actual mussar workshops for developing elevated character traits. The core of Rav Wolbe's method is the continuous need to better oneself in the everyday life by contemplating nature, surroundings, political events, and one’s home life.
