Marley Dias is an author, public speaker and the youngest member of Forbes' "30 Under 30" this year -- and she's not even in high school yet. At the age of 10, Marley started a campaign called #1000blackgirlbooks because she was frustrated that she hadn't read books in school featuring black main characters. She set out to collect books featuring characters that look like her and received more than 11,000. Now, the 13-year-old has a new book called "Marley Dias Gets it Done and So Can You!" Dias joins "CBS This Morning" to discuss what she hopes to achieve with her book and why she launched a campaign about racial harmony.
