Rav Yitzchak Zilberstein told a story in his Sefer בך בטחנו about a great Admor who appeared to his son in a dream a year after he passed away to give him a message. The son asked his father to tell him what it's like in the upper world. His father was not able to reveal too much, but he did tell him that the reward for every little deed that we do is tremendous, even for little things like getting a chair for someone to sit on, serving a cup of water or giving someone directions. We have no comprehension of how great the reward for these minor deeds are, all the more so for deeds that are more difficult to do. He said further, if someone sings a song of praise to Hashem, even if he's sitting at a Shabbat table all alone, it is as precious to Hashem as the Leviyim singing to Him in the Beit Hamikdash. We can't imagine how great even one Amen is. A man by the name of Mati had to deliver an envelope to someone who worked in a bank in Tel Aviv. When he arrived he was told the person he needed was in a meeting. In the meantime he sat down to eat an apple. He was accustomed to always saying all of his berachot slow and loud, so right there in the bank he made the beracha out loud. One of the bankers there went over to him and said, "What are you yelling? This is not Bnei Brak, please talk quietly." A few days later he returned to that bank with another letter to deliver and once again he had to wait. This time he said his beracha quietly. The same banker saw him and said, "Why did you say the beracha so low? I wanted to hear it." Mati told him he was only following orders. The banker then told him he used to be religious but he lost everything. Last week when he berated him for saying the beracha out loud, his mother came to him in a dream very angry saying how much suffering he was causing her in the upper world. She then said, "If you would have answered Amen to that beracha, it would have elevated my soul so much. But instead, you yelled at the person for doing it." The banker then told Mati he couldn't believe that even an amen from someone like him would be meaningful. The banker then apologized and gave Mati something else to make a beracha on so he could answer Amen. Hashem appreciates every little deed that a person does and will reward him greatly for every one of them. How much more so if the deeds are difficult to do. A rosh kollel in Lakewood recently told the following story about one of the students who learned in his kollel who we'll call Yehuda. Lo aleinu, Yehuda's wife had a miscarriage at a late stage. The rosh kollel told Yehuda to take off as much time as needed to be with his wife and give her support. This was on a Friday. On Sunday morning Yehuda was back in the kollel learning the full day. The rosh kollel asked him about it. Yehuda told him they were inspired by a statement from the Zohar: " חזו בני חביבי דמשכחין בצערא דילהון ועסקין בחדוותא דילי - Hashem says, "Look at my precious children. They forget about their own sorrows and they take delight in my Torah." They wanted to fulfill that precept and bring pleasure to HaKadosh Baruch Hu. So the man's wife encouraged him to go learn. The very next day Yehuda received a call from a cousin of his asking if he could borrow his violin. The cousin came to pick it up. Before leaving, he wanted to test it out. This cousin had no idea what was going on in Yehuda's life with the miscarriage. He then started playing a song and the words were " חזו חזו בני חביבי "- the very same words that had just inspired Yehuda and his wife to go learn. They felt Hashem was talking to them directly telling them how much He appreciated that sacrifice. Our deeds are so valuable, and therefore we should do every one of them happily and enthusiastically.
