Two Figs
A person who first faces himself honestly is no longer shaken by what others think of him.
The Yehudi liked to say that every person should keep two figs. The first he shows to himself, and the second he shows to the world. A Jew who has first faced himself honestly, and knows what he really owes Hashem, is no longer shaken by the opinions of other people. He can then stand before them calmly, offering what he chooses to offer. In the Peshischa way this was not stubbornness but a form of inner truth. Service of Hashem is measured by the standard of one's own conscience before Him, and the crowd, whether praise or scorn, cannot move that standard.

Before you act today on something where others will have an opinion, take two quiet minutes alone. Ask yourself what Hashem actually asks of you here, and answer in one honest sentence. Write it down if that helps. Then go and do it without arguing your case to anyone. If someone criticizes you, remember that you have already looked at the matter squarely. You can listen politely, learn from whatever is true in the comment, and still keep your steady course.
