In Part 2 of J. Cole's Bornsinner.com series, Kendrick Lamar talks about his childhood, the importance of J. Cole's music, and recounts advice he once received from Erykah Badu.

"It's a sin for me not to be doing what I'm doing," Lamar was once told. "Everybody can rap, but only a few get in these positions where they can really speak to a generation of people. When I listen to people like Cole, it's that gift," he added.

The Born Sinner series tells the stories of the people who were instrumental in making his upcoming "Born Sinner" happen.
