I think, especially living in L.A., it's very easy to get wrapped up in weekend announcements and the trades and the whole social life of the city, and to get divorced from what actually matters.

There are a few musicians that I know who seem on the outside like very asocial or somewhat unemotional people, people who aren't capable of emotions, and people think they're very cold inside.

Before 'Whiplash,' I'd had a string of failed scripts. I'd pour my blood, sweat and tears into them, and no one would like them.

If there's a good review, I'll skip over the headline, but I always find the bad reviews and read those. I don't know why. It's a little sick and demented.

I like the idea of working my way up. I don't feel impatient to immediately jump into something that could literally bring down a studio if I don't do it well.

Nothing is guaranteed to last, so you should just enjoy it as it happens.

I tend to latch on to things and not let go.

What's great about musicals is their energy and go-for-brokeness - stopping the story to sing and dance. How can you not love that?

My dad is a big jazz fan, and that was the reason I first got into jazz.

What I love about jazz is that it's full of legends, full of myths. It's an oral history because it started in New Orleans and Kansas City, under the radar.

First time that I cried at a work of art was at a drum solo that I saw. A drummer named Winard Harper, part of the Billy Taylor Trio, gave back in - I would have been in high school - 2005 or something.

I like movies that are specific. Movies that home in on a very specific subculture, a specific discipline, a specific world.

I guess art itself is insane. Its actual function is rarely clear, and yet people give their hearts and souls and lives to it, and have for all of history.

My hands were constantly blistered or bloody; my ears were always ringing. I tore through drumheads and drumsticks like there was no tomorrow.

I've always wanted to make movies that are fever dreams.

I feel like a lot of directing is casting.

Mozart was born Mozart. Charlie Parker was born Charlie Parker.

In some ways, jazz is the most precise of art forms and the loosest in the sense that it's all about improvisation, but the musicianship required is kind of insane. To actually play with real jazz musicians is a different level of musicianship that almost has no equal in any other form of music in the world.

Real practice means working on stuff you're not good at. Real practice is about butting your head against the wall repeatedly until you get it right.

I was really trying to sell to people who hate jazz: to make a case for the art form as youthful and energetic, not the sort of rarified intellectual activity it's painted as.

I love movies where you can sense that the director risked biting off more than they can chew.

'La La Land' is about the city I live in. It's about the music that I grew up playing; it's about movies that I grew up watching. Even the big spectacle of the movie feels private to me in that way.

I love the idea of thinking of cinema as not that far from music. A lot of my favourite movie makers, the way they move their cameras or the way they cut just feel very musical - even if the movies have no music in them at all.

There something to be said for having even unrealistic dreams. Even if the dreams don't come true - that, to me, is what's beautiful about Los Angeles. It's full of these people who have moved there to chase these dreams.

I like movies where you feel like it was actually thought through.

I was always pretty decent at fast stick work or doing stuff that seems impressive that's not really; I was pretty tasteful and had good ideas musically. But I had a terrible sense of tempo, which is like being a blind painter. The conductor would just rip into me, and it lasted for years.

I didn't have traditional stage fright. If there was 500 people in the audience or three people in the audience, it didn't really make a difference. What made a difference was the conductor. Everything that I was scared about as a drummer was him. It was his face. It was whether or not he'd approve of my playing.

When someone is playing drums, they aren't actually moving around a space; they're just moving their arms and limbs. They're stuck behind the drum set. So to film someone playing the drums and make it feel as kinetic as a car chase or a shootout or a battle scene was the challenge.

I'm too self-serious for a comedy.

Certainly, grades only matter so much when you're in Hollywood. But I became an utterly motivated, devoted, committed student. I was a good student because I was convinced that it would somehow help me in my quest to become a filmmaker.

I remember moving out to L.A. straight after college and just starting to try to write scripts and trying to get stuff off the ground.

Whiplash' was just a lucky kind of convergence of events in that I'd been trying to get a bigger project off the ground with no success for a while, and then finally, out of frustration, I just wrote this leaner, meaner, personal script about my experiences as a jazz drummer, and that's the one that wound up getting made.

I never desperately wanted to be a jazz drummer. If anything, I was motivated a lot by fear. Fear of the conductor, fear of the future.

There's something very particular about the kind of rage you feel when you're alone in a practice room by yourself, unable to master a simple thing like a rudiment. You keep trying to master this very basic thing, and when you don't get it, you just scream. I broke a lot of drum heads, and I broke a lot of sticks.

There are no large-scale original musicals being made right now. They're all Broadway adaptations and jukebox musicals or catalog musicals, and they just don't interest me as much.

You're only the boss if you put up your own money.

A real man won't ask or answer questions about another man's money.

It's important for people to believe in themselves.

Work harder than everyone, be patient, and just know that if you're going to do something on your own, you're gonna have to feel some pain.

I always knew that content was the best way to sell things, but my thing was, why sell other people's stuff if I have a point of view?

You speak things into existence, but there's a gift and a curse with that. You got to be careful what you say.

I'm not one to be paying too much attention to what another dude's doing.

'Hustle & Flow' came out, and I was really rooting for 'Hustle & Flow' because, you know, it was a hip-hop movie, and it was a good movie. It was well acted.

How can another man call another man boss? That's like calling another man 'Daddy.'

I don't complain about other people's game - I just create my own.

Number one, I am a true movie maker. And, you know, I am very much - I don't want to say infatuated, but I'm impressed with the art of making a movie and invoking emotion. You know, when I started making movies, I thought it was easy, and then when I got into it, I was like, 'This is not easy at all.'

I'm never gonna owe money because every time I get a dollar, I put it into another business, whether it's to buy goods or develop other companies. You don't have money; you have companies. That's one business model. That's mine. And I only associate with other people that are putting up their own money, 'cause they're the only ones that can relate.

The worst disrespect of all time is to disrespect someone's children.

It's important to be enlightened.

I'm a businessman who puts up his own money, so I don't have time to hear about emotion. I gotta get right to the point. I'm going to tell you the truth, I'm going to address the elephant in the room, and we'll all move forward.
