This means volunteer, assist, help out. People who volunteer on a regular basis as part of an ongoing commitment to a worthy organization or cause like Friends of the Library or the Humane Society are performing a valued service and are rewarded with friendships, satisfaction, and personal growth. People who routinely assist others in meeting their needs as friends or caregivers build good karma and make the world a better place.

And some happy souls simply express in their very nature a generosity of spirit that William Wordsworth called, "feelings too / Of unremembered pleasure: such, perhaps, /  As have no slight or trivial influence / On that best portion of a good man's life, / His little, nameless, unremembered, acts / Of kindness and of love."  Such acts enlarge and enrich all who are touched by them.

Activity

For a week, look for opportunities to volunteer, help out, lend a hand to an individual or group without expecting any reward or repayment. You don't have to take up every one of these opportunities; after all, people sometimes need to learn to do for themselves, but try to find a few situations in which you can be of genuine assistance to another, and help.
