"The trouble is that when you read criticisms about the other films that I've made you get the impression that they're all about themes, or problems, or ideas. But those are actually things that develop out of characters, out of images and out of other things. These more abstract things develop while working on the material, and out of it. It's not a theoretical exercise from the outset."

Happiness can seem like an abstract, transcendent notion, but in fact, I found that getting enough sleep (very important!!), getting exercise, not letting myself get too hungry, not letting myself get too cold (I'm a person who is always cold), made a big difference. Partly because I felt happier, partly because feeling physically comfortable makes it easier to keep other difficult happiness-boosting resolutions like biting my tongue.
