It's good if we can help others in our everyday lives. Be it the homeless, the elderly, the sick or children. Everyone can use help at some point.
If we cannot help ourselves, we can empower others to do so.

I know many who took part in the following organization and once had a very small part in a  Hope Youth Corps. That's why I know the enthusiasm and strength behind Hope worldwide and recommend donating or taking part here:
