I thought this was a really critical challenge for Stephen. He is such a wonderful guy and clearly he is an incredible giver. But, as he said himself during this episode, he hadn't been very involved in local charities before this competition.

I went to Stephen's fundraiser for the Northern Westchester Shelter and I got to meet his wife and daughters. I was so amazed by the girls—they could have had posters of the latest teen idols hanging on their bedroom walls but instead they have maps of Africa with pushpins of all the places that they support. That's some great parenting. But, Stephen had never really realized that there were people in need in his own backyard, and that he doesn't have to head to Africa to give big.

That's what this challenge was about – showing the givers, and our viewers, that people in need are everywhere. By the end of the challenge, Stephen absolutely understood that. All the givers did, and I hope that everyone watching at home will too. I say it time and time again, but I think it bears repeating: You don't need to be rich to give back. You don't need to travel around the world. Everyone has the power to be a big giver, and that's what's so exciting. Giving is empowering, and it's accessible to everyone.

One episode to go! I'm sad this season is almost over, but so excited for the winner to be revealed. Who do you think will be the biggest giver? Tune in next week to find out!
