Her best advice: “If you’re craving a way to use your time, voice, or money to help others at the end of this difficult year, I highly recommend a gift to one of the thousands of organizations doing remarkable work all across the country. Every one of them could benefit from more resources to share with the communities they’re serving,” Scott wrote on Medium. “And the hope you feed with your gift is likely to feed your own.”
