Comparing Yourself To Others

Why should you consider yourself better than other people? If it is because of your upright stature, everyone was created in the image of G-d, just like you. If it is because of your family, all of us are the children of one man, the children of Avraham, Yitzchak, and Yaakov. If it is because of your wealth, there are many people more empty-headed and impulsive than you who are wealthier than you. In addition, it is G-d who makes people poor or wealthy.

(Sha’arei Kedusha)
