Chelsea Clinton's message to women for International Women's Day: 'We have to keep going'

Clinton is the author of a new children'sbook, "She Persisted Around the World."

"Particularly at this moment, in 2018, when we have so many women who are raising their voices around the world, so many women here in the United States who are running for office," Clinton said, "my message is thank you and we have to keep going."

Clinton, 38, is author of the number one New York Times bestselling picture book, "She Persisted: 13 American Women Who Changed the World."

Clinton's new book, "She Persisted Around the World: 13 Women Who Changed History," celebrates women from around the world who have made a difference and inspired others.

International Women’s Day is an annual celebration of the movement for women’s rights and equality.

The day is also a time Clinton thinks that citizens of the world should "take stock" of what they are doing for girls and women.

"Whether that’s in terms of educational opportunities or employment opportunities, getting health care, including the reproductive health care that every woman around the world should have access to," she said. "How we’re doing in terms of women in leadership positions in every sector, in every country across the world so that we really have a clear sense of what the gaps are for whether or not girls and women are given an equal shot, equal opportunity, equal affirmation to the boys and men in their families or communities."

Chelsea Clinton believes that women's initiatives have advanced in some ways, but there are still many women who haven't been reached.

"I just think that, while we’ve made progress, we have so much work to do until every girl and every woman is protected, supported and empowered to be whatever they want to be in the world," she said.

When asked what advice she would give her 16-year-old self, Chelsea Clinton said she wished she had been "less afraid."

"I think I always knew that persistence was really important," she said. "I just wish I had been a little less afraid when I was younger."
