HuffPost Impact is looking for nominees for our Greatest Person of the Day. The recognition honors acts of service that go above and beyond -- from local heroes performing selfless acts of courage in their communities to global trailblazers embarking on humanitarian efforts worldwide.
Perhaps your neighbor has been quietly volunteering at the local food shelf for 30+ years, or your friend selflessly saved someone's life in an accident, or someone you know started a school to teach math in Africa. If you know someone who is making small changes that are leading to big differences, nominate him or her below. If chosen, we'll reach out and name this nominee our Greatest Person of the Day!
