J.K. Rowling, author of the wildly successful “Harry Potter” books, is no longer a billionaire because she has given so much money to charity.

Rowling struggled with poverty herself for years before her books became hits, and in 2004, her earnings from the books and films based on them skyrocketed her onto the Forbes Billionaire list. She remained on the list for the next seven years, but she made huge charity donations during that time as well.

“You have a moral responsibility when you’ve been given far more than you need, to do wise things with it and give intelligently,” Rowling said.

Rowling has given to numerous different charities, particularly those related Multiple Sclerosis, and she’s also built a regenerative neurology center in Scotland. She also created Lumos, a charity that has helped tens of thousands of orphaned kids, both in reuniting with their families or finding a new place to call home. The charity has helped over 20,000 children stay with their families rather than being sent to orphanages.

As someone who was once a struggling single mother herself, Rowling often donates to One Parent Families as well, describing it as one of her favorite causes.

“Raising children in an orphanage or other institution harms their health and development. It increases their exposure to abuse and puts them at risk of future criminal activity,” she wrote on her website. “Children in orphanages are isolated. They are isolated from their families and their communities. They are often hidden behind walls and segregated. Even when orphanages and institutions are set up with good intentions, care is tailored to the needs of the institution, not the child. Staff struggle to cope with high numbers of children, particularly those with complex needs. Physical contact, care and attention become a luxury.”

Rowling may no longer be a billionaire, but nobody can say she doesn’t have a big heart! Watch her talk about her charity work in the video below.
