People easily deceive themselves into thinking that they are doing an act of kindness for the sake of kindness, when in fact this is not the case.
The way to test your motivation is to see if you are equally willing to go out of your way to help someone who will be totally ungrateful. When you don’t derive any personal benefit from your act of kindness and you still help others, it is a sign that your goal is to help others for their sake and not for your own. ~ R’ Yeruchem Levovitz zt”1
