We all want to make a difference and there’s no reason to reinvent the wheel. The nonprofits listed here make it easy to find the right ways for you to get engaged and change lives. You can choose from one-time opportunities like writing letters to hospitalized kids to ongoing commitments like online mentoring of first-generation college students. This is not meant to be a comprehensive list. It’s a list of nonprofits that I personally vetted and included in my book HumanKind: Changing the World One Small Act At a Time. Easy to work with and responsive to emails, these organizations provide great opportunities for individuals and families.
