What advice would Charlize Theron give her 18-year-old self?

California’s WE Day 2016 at The Forum in Inglewood was a day to celebrate youth making a difference by bringing some of the biggest names in Hollywood together with 16,000 students. Academy Award-winning actress Charlize Theron, star of Mad Max and the upcoming The Huntsman: Winter’s War, took the stage to talk about #genendit, the movement for this generation to end AIDS.

At the press conference, I had the chance to ask her what advice she would give to her younger self, to which she responded, “Chill out!” Take a look below:

She is also the Founder of Charlize Theron Africa Outreach Project (CTAOP) and Honorary Co-Chair of WE Day California.

WE Day airs commercial-free on ABC, Sunday, August 28, 2016 at 7pm ET/6pm CT.
