With experience, you suddenly realise you know how to do things or that you've done something like this before. And I think as you get more confident, you can sit back and try and weigh up the options of doing something or not doing something.

I think most people have experienced that at some point: being on one end or the other of a super-unbalanced relationship.

I think everyone should experience defeat at least once during their career. You learn a lot from it.

“But focusing on the experiences that create superfans is more important than any other activity in your business. It’s more important than getting more traffic, more followers, more views, or more subscribers. It’s even more important than building your email list and acquiring more customers. Why? Because when you focus on creating superfans, as a byproduct you’ll get more traffic, more followers, more views, and more subscribers. You’ll build a stronger, more targeted tribe who will go out of their way to support you and what you do.” 

Charles Schultz is a really interesting case. He wrote that comic strip and drew it himself from beginning to end, and it's a work of genius. It's very simply drawn, but it has some really deep emotions that you don't expect in a silly-looking comic strip.

The conundrum that I face on a daily basis is that I have two sons who have grown up watching 'The Simpsons,' so they know exactly what buttons to push. They know how Bart irritates Homer, and they use these lines against me to tell me that I'm not funny anymore.

I like all of the early relationship strips that were collected in 'Love Is Hell,' where I pretended to be an expert in relationships and did comics like 'The Nine Types of Boyfriends,' 'Sixteen Ways to End a Relationship,' 'Twenty-Four Things Not to Say in Bed,' and other arbitrarily numbered lists.

We did 'The Simpsons Movie,' which took almost four years; it was the same people that do the TV show, and it just killed us. So that's why there hasn't been a second movie. But I imagine if the show ever does go off the air, they'll start doing movies.

I know for a fact, obviously, because my kids grew up watching the show, that there are some things they are introduced to from 'The Simpsons', and then later in life they see the thing we're parodying. My kids had not seen 'Casablanca,' and we'd done parodies of 'Casablanca.'

'The Simpsons' basically - and 'Futurama' - are really smart shows. They're kind of disguised as these goofy animated sitcoms, but the references within the shows, if you're paying attention, are pretty smart and pretty sophisticated.

The nice thing about 'Futurama' for me personally was that it was a way to honor some of the traditional ideas in literary science fiction, not so much movie or television science fiction - although we have that too, obviously. Our situation, a workplace comedy, led to all sorts of stuff.

'The Simpsons' was about children and married parents; 'Futurama' is about people in between; they're growing up and haven't settled down. Every other cartoon show seemed to be, you know, dumb dad, bratty kids.

I loved literary science fiction. In fact, as a kid, when I was reading science fiction, I thought 'I can't wait for the future when the special effects are good' to represent what was in these books by Arthur C. Clarke, Alfred Bester, Philip K. Dick, J.G. Ballard, Jack Vance.

With 'Futurama,' I was just worried that somebody would beat us to it; it seemed so obvious that there should be an animated science fiction show set in the future. And one of the reasons why it's not, I learned, is that it's really, really difficult.

With 'Futurama,' I wanted to do unrequited love, and David Cohen agreed, and although our original plan was never to have Fry and Leela get together, we finally just said, 'You can only string the fans along so far.'

'The Simpsons' obviously is a huge success, and Fox has nothing to do with its success, with its creative success, and as a result they don't really like the show. They don't like 'The Simpsons' at Fox.

My father was a really sharp cartoonist and filmmaker. He used to tape-record the family surreptitiously, either while we were driving around or at dinner, and in 1963 he and I made up a story about a brother and a sister, Lisa and Matt, having an adventure out in the woods with animals.

Back in high school, I wrote a novel about a character named Bart Simpson. I thought it was a very unusual name for a kid at the time. I had this idea of an angry father yelling 'Bart,' and Bart sounds kind of like bark - like a barking dog.

I had been drawing my weekly comic strip, 'Life in Hell,' for about five years when I got a call from Jim Brooks, who was developing 'The Tracey Ullman Show' for the brand-new Fox network. He wanted me to come in and pitch an idea for doing little cartoons on that show.

I think 'Family Guy' and 'American Dad' have definitely staked out their own style and territory, and now the accusations are coming that 'The Simpsons' is taking jokes from 'Family Guy.' And I can tell you, that ain't the case.

Our solution on 'The Simpsons' is to do jokes that people who have an education, or some frame of reference, can get. And for the ones who don't, it doesn't matter, because we have Homer banging his head and saying, 'D'oh!'

It's a funny show. The characters are surprisingly likable, given how ugly they are. We've got this huge cast of characters that we can move around. And over the last few seasons, we've explored some of the secondary characters' personal lives a bit more.

With Charlie Brown, it was about loneliness and isolation. I always thought that the thing about Charlie Brown and those characters was the absence of the parents. Half the strip was about who wasn't there. The parents were never in the picture.

Nihilism in American comedy came along way before 'The Simpsons.' There was a fairly nihilistic point of view to 'Saturday Night Live,' for instance, back in the beginning, and a lot of really dark comedy had a really anti-sentimental take on life.
