I authored the national bestseller HumanKind: Changing the World One Small Act a Time, which is full of true stories about how one small deed can make a world of difference. Forbes called HumanKind, "The most uplifting and life-affirming book in years." and NPR said, "You're going to love this book." (Thanks!). HumanKind has been featured in PEOPLE, The Wall Street Journal, FOX, USA Today and others.I regularly speak to companies, churches, temples, nonprofits and book clubs, and all proceeds from my speaking engagements and book sales go to Big Brothers Big Sisters.In addition to Big Brothers Big Sisters, I'm deeply involved with the nonprofit Hopeworks, where I teach entrepreneurship. Everyone in my class starts their own company, which has led to many adventures in business.I enjoy advising and investing in startups, writing, and volunteering with nonprofits that serve youth.
