Rav Nosson Zvi Finkel, the Alter of Slabodka
The first resolution that R’ Nosson Zvi wrote down in his diary was “to try to be extremely careful of my fellowman’s honor, with patience, with a soft answer, never once to get excited… not to embarrass anyone in public… to find ways daily, at the very least weekly, of benefiting my friends.”
