There's this perception that if you worry a lot and if you look really busy and stressed out then you'll be more successful. You talk about how little sleep you get and how tensed you are and how you're not getting the appreciation you deserve.

Movies don't look hard, but figuring it out, getting the shape of it, getting everybody's character right and having it be funny, make sense and be romantic, it's creating a puzzle. Yes, having been a writer for so long, I have an awareness of when things are going awry, but it doesn't mean I know how to fix them.

Like most struggling writers trying to get their scripts commissioned, I had to do something odd to pay the rent. So, aged 21, I started up my own small cheesecake company in Philadelphia.

Being part of a team helped me so much. I know the fact that there was a man in the room with me all those years made the medicine go down. I had made the companies money. I didn't have to start, like a lot of women, from ground zero. My path was not the same as a woman starting out by herself.

Sometimes when I'm writing I'll play Cole Porter, just because the rhythms and the lyrics are so perfect that it's like having a smart partner in the room. I have a huge collection of music that I listen to when I'm writing, and I also prepare a lot of music before I start directing. I put it all onto an iPod that I have with me on the set. It's helpful to the actors, because for an emotional scene, I'll play it and say, this is how it feels, to keep us in the zone.

There's a hardening of the culture. Reality TV has lowered the standards of entertainment. You're left wondering about the legitimacy of relationships. It's probably harder to entertain the same people with a more classic form of writing, and romantic comedies are a classic genre.

I like to eat meals I will remember. Otherwise, whats the point?
