On Being Quiet About Donald Trump:
"I mean, it's like beating a dead horse. We already know what it is. Are we gonna keep talking about it or are we gonna take action?" Lamar boldly asks. "You just get to a point where you're tired of talking about it. It weighs you down and it drains your energy when you're speaking about something or someone that's completely ridiculous. So, on and off the album, I took it upon myself to take action in my own community. On the record, I made an action to not speak about what's going on in the world or the places they put us in. Speak on self; reflection of self first. That's where the initial change will start from."
On Ghostwriting:
"I called myself the best rapper. I cannot call myself the best rapper if I have a ghostwriter. If you're saying you're a different type of artist and you don't really care about the art form of being the best rapper, then so be it. Make great music. But the title, it won't be there."
On If He Knew Bad Blood Was About Katy Perry:
"No, I wasn't aware of that, bro. That's a great question. No! On the record, no. Which makes it even more funny now, for sure. That's far beyond my concern. I have to stay away from that, for sure. That's some real beef [laughs]."
On What He Learned From Working With Beyoncé:
"How particular to be about your music. She's a perfectionist. Think about the BET performance. She was very particular – the lighting, the camera blocking, the transition from the music to the dancing. It was confirmation of something I already knew."
On The Future:
"I'm mothafuckin' optimistic for sure. I wouldn't be here if I wasn't! Come on, man, this shit don't happen to everybody. Almost all of my best friends are in prison. Forty years plus. Every show, they wanna see pictures. They tell me, "You gotta be optimistic as fuck to be where you at. We didn't have that. The glass was always halfway empty." And it's not just being optimistic. It's really about being responsible. You can talk about dreams all day and "what I want," but you gotta put an action behind it."
