If you can't think of anything then think again.
I took my kids to a park today in a nearby neighborhood which is probably 75% jewish, almost entirely comprised of people who haven't (yet) found a life of torah & mitzvos. While it's saddening to see so many who haven't been exposed to what we have, at the same time I also felt incredibly grateful for the fact that we do have the opportunity to live life the life that we have. Seeing so many of our brethren who sadly have not found this path made me feel especially thankful for what I have.
What made you happy today?
