Yes she's the only person who donated herself out of being a billionaire.
She's one of the very few people to still live in their native country and pay full taxes instead of tucking it away in the cayman's.
She funds her own charities like Lumos who have a 100% donation guarantee which means it is one of the few charities where the total of your donation goes to the actual cause instead of for example just 10 cents and the rest to PR/admin/employees.
She funds a woman's shelter so it's not dependable on government funding.
She vocally stands up for women's rights.
She is a hero and an amazing role model for all girls.
