On Friday, the 19-year-old Pakistani activist, who has fought for girls’ education, attended her last day of school in Birmingham, England.
After achieving this milestone, Malala joined Twitter — announcing she would be travelling to the Middle East, Africa and Latin America to meet the girls she’s been fighting for.
"Today is my last day of school and my first day on Twitter," she wrote.
"Graduating from secondary school (high school) is bittersweet for me. I'm excited about my future, but I know that millions of girls around the world are out of school and may never get the opportunity to complete their education."
Malala called on her Twitter followers to join her in fighting for the rights of girls around the world.
"Each girl’s story is unique — and girls' voices are our most powerful weapons in the fight for education and equality," she wrote.
