The heresy of not believing that Hashem created unique neshomos. It's irrational to look down upon someone because they're different from you. When we lose our temper, we're not ourselves. Appreciating the good in ourselves. Two views on punctuality. The danger of hiding behind leshem Shamayim (for the Sake of Heaven). Holding on to the wrong argument for our own sake. In Eretz Yisrael, differences are magnified. Externalities in shidduchim.
