"my friendships are my foundation. they are my family. tell your friends you love them and acknowledge them for standing by your side no matter what. #DoGood#BeGood," she added before nominating a group of people "to share a random act of kindness."

"Doing good goes both ways, this challenge we'd like you to keep in mind that whether you're doing good for others, being good to yourself is also important," the organization captioned the throwback photo of Meadow and Paul. "We'd love to hear from our PW family!"
"We will be giving away merch and gift cards to participants who submit their “Do Good” stories to share. Let's Do Good together! Tag us and add the hashtags to enter. #DoGood for others #BeGood to ourselves. #happybirthdaypaul."
Back in March, the Paul Walker Foundation partnered with Los Angeles Regional Food Bank to "provide meals for children during the COVID 19 crisis," Meadow announced on Instagram at the time.
"Please stay home," she added. "This protects not only you, but everyone around you. We need to lookout for each other during this time. And all times. Lots of love, Meadow."
