Start a social group to have fun while brightening lives with generosity. Research shows that those who help others are more likely to feel happy about their lives. And when you include people of all ages, you can catch up with pals and help kids understand the value of service. Here’s how to start:

• Choose an activity. Begin with a task that will take only a couple hours. You might ask attendees to bring donations for a local book bank, school, or library. Other ideas include handing out free lemonade on a hot day or delivering extra veggies to neighbors.

• Set a date. Pick an evening or weekend and send out your invitations. Start a club webpage so you can post ideas for future projects.

• Keep it going. Studies find volunteers who give the most time feel the greatest well-being. Each week, brainstorm with members for new projects. Who could use extra help? Your group could make and freeze meals for a new mom, do yard work for older folks, or household chores for a busy family.

Consider how you will change someone’s day with a little kindness.
