Do you Tweet? Chat on Facebook? Interact with friends on other social networks? Then you have a medium for getting people interested in making this a better world. Continue sharing tidbits of your life, but add a dimension. Mention an informative article you read in the newspaper about how widespread hunger is in America. Express your surprise at learning how many people in your town are without shelter each night. Refer friends to a book you thought had an interesting approach to climate issues or a place you’ve begun volunteering at. Sum up that conversation you had about elder abuse. Don’t be detailed or political. Your aim is not to start an argument but to get your friends thinking. Also, do it only once in awhile. If people think of you as being always on a soapbox, they’ll stop reading you. Most important, let people know that you do care about making this a more peaceful, caring world—and that you hope others do, as well.
