ובכל יום ויום מרדכי מתהלך לפני חצר בית הנשים לדעת את שלום אסתר - Every day for four years Mordechai walked outside the house of the women with great concern over the fate of Esther. If he hadn't done this there would be no Purim miracle. [Maharal]
We sometimes forget about others who are in dire straits. Mordechai didn't.
Our brother Gilad [ben Aviva] Shalit has been in captivity with wild animals for a walloping 1716 days!! Let us try not to forget him by forgetting about our own problems and focusing on him and how he and his poor parents must feel. A perek of Tehillim or ten are also suggested.
[Based on the words of the Tolna Rebbe Shlita Melave Malka Parshas Pekudei 5771]
