"I've had wonderful influences in my life – my parents, my brothers and sister – and I just thought at a very young age if you don’t have that, you might as well throw in the towel ... I think at the end of the day your family is all you’ve got. There’s lots of fights and disagreements, [but] I come from an amazing family."
Anthony Shriver, carrying on his and sister Maria Shriver's annual tradition of participating in the Best Buddies Challenge bike ride from the JFK Library in Boston to the beach in Hyannis Port this weekend, told PEOPLE his secrets to success. The father of five started Best Buddies International, which promotes friendships for people with intellectual disabilities, in 1989.
