Be very happy, and treasure everything you do in the service of Hashem. 

Think, “I wouldn’t trade this merit for all the money in the world!” 

This applies even to a single good word, thought, or deed. Though it may take only a moment, it is never lost; it will accomplish great things for you and perhaps for the entire Jewish nation. 

What greater joy is there than fulfilling the purpose of creation? Do whatever you can—whether big or small—as people say, “Whatever you take from the marketplace is worthwhile.”

~ The Beis Aharon zt”l
