While I was young, when I burned with the love of God, I thought I would convert the whole world to God. But soon I realized that it would be more than enough to convert the people who lived in my town, and I made an effort for a long time, but was not successful. Then I realized that my agenda was still too ambitious, and I focused on the people in my household. But I could not convert them either. Finally I realized: I must work on myself, if I'm really going to have something to offer God. But I didn't even accomplish this.
—Rabbi Chaim Halberstam of Sanz
