Writing is like falling in love. When you first meet, the butterflies distract you from what's underneath, what's real. Then you find a comfort zone and, (in your best sweats with a bowl of ice cream), get a little lazy and the writing suffers because of it. With some projects, you'll put that unfinished novel away and part on good terms and with others, you might curse and scream things you don't mean in an effort to win your way back into good graces.
I think there are two types of writers: Finishers and Failures
The Finishers are the ones who sit at the computer everyday, even when they don't want to. They learn, and revise, and perfect, and revise. They're determined to DO instead of SAY. They get feedback from others, market themselves well, and press on when all seems impossible.
The Failures are living among us. They dress like we do. They write like we do. They even get as far as we do. The big difference is, they never completely accomplish anything. They talk about doing it, but something always comes between said Failure and living the dream. Excuses.
