Jewish survival and Jewish revival begins and ends in the Jewish home. Light Shabbat candles on Friday night. As a family, visit a nursing home. Find out who has no one to visit them and bring them a card at the next holiday. Children can make their own cards.
Stocks are an investment, and tzedaka is too.
As a family, choose one or two charitable causes you would like to help, and then put aside a jar in your kitchen into which everyone can deposit some money on a regular basis. Once every few months, gather the money and send it to the organization. Include a note asking if there is any new information about the activities of the cause you are supporting. When that information arrives, read it together and watch your investments grow. If you are single, your house is still a Jewish home and an important part of the Jewish national family.
