"Growing up we had a lot of insecurities," Serena says. "Even now we still have so many insecurities. It's not like we're perfect. ... [We want] to let [teens] know that celebrities and stars, not only just us, but everyone has these issues as well."
Venus says that to this day, she still works on coming out of her shell more, and looks to her sister, Serena, as a role model for self-confidence.
"I had a hard time making friends, because I was really shy, and I still am shy," Venus says. "That was one of the ways I always wanted to be like Serena. But you do have things that you struggle with. You can't be perfect in everything. I found out, sure, maybe I didn't have as many friends, but it was something that I could work on."
