The money of your friend should be as precious to you as your own. If a person sees his friend’s possessions in trouble—for example, if he sees his friend’s house being burned down—he has to do something and be proactive to save it, as he would for his own property. When you treat your friend’s possessions with respect, obviously you’ll come to respect him himself, and that would lead to peace and harmony between individuals, which is what the Torah promotes.
Secondly, apply yourself. Work very hard to learn Torah; push yourself very hard to get involved in Torah study, because it’s not an inheritance for you. A person could think, “My father was a great sage, my grandfather...” It’s coming to me automatically; I’m going to inherit Torah. Torah doesn’t work like that. If a person doesn’t apply himself and work hard on his own, then he’s not going to become a Talmid Chacham (Torah scholar), and he’s not going to take advantage of what the Torah is trying to give him.
And lastly, all of your actions should be for the sake of Heaven. A person shouldn’t compartmentalize a little bit with Torah: “Oh, Torah is for synagogue, it’s for the study halls, for the Beit Midrash (study hall), but when it comes to the rest of my day, there’s nothing to do with religion, nothing to do with Hashem.” But even when a person is eating, drinking, or working, he has to really think, “I’m not doing this just to enjoy or just for pleasure, but I’m doing this to be strong, so I have the ability to do the will of my Creator, to do the will of the Almighty.” A person should try to have that Kavanah (intention) in everything that he does, as the Pasuk (verse) says: in all of your ways, all of them, including the seemingly mundane tasks or actions that you’re involved with.
