Rekindling your desire to write

What do you do when you feel like you've lost the motivation to write? Not because you have writer's block necessarily - but just that fundamental desire to put pen to paper, or fingers to keys?

How do you rekindle your desire to write?

I've been trying for about a month to get my passion back. I've found that I go through these periods where I WANT to write, but I just can't force myself to get focused enough to. My biggest problem is getting enough motivation to actually sit there and write. Another problem I have is coming up with ideas. A lot of times I will hear a song or see a movie and get inspired to write, and I even jot down a rough plot sometimes, but I very rarely follow up on it. 

I get distracted by the Internet very easily. I'll sit down and tell myself that I'm going to write, and then I end up checking my e-mail and sending some out, browsing sites, or talking to people, and I forget. I joined this community, along with a few others, in an attempt to get my desire back. Prompts usually help me a great deal, but like I said, I get distracted way too easily. Once I get started writing, I'm usually good, but lately that just hasn't been happening.
