I find that knowing what to do next helps. Also, I try to make a habit of getting to work when I first turn on the computer (rather than going to Hacker News and whatnot) in the morning. This helps me get some momentum, which helps keep the work going throughout the day.

I can still get work done without the initial early morning momentum, but I get much more done by focusing on work first thing.

For "what to do next," I keep a task list. I've been using "The Hit List" on Mac and ToDoList (by AbstractSpoon) while in Windows. I find that part of the trouble with "getting started" is not knowing what to do next sometimes. So keeping a task list is quite helpful, in my opinion.

The other thing is, setting up timeboxes and being resolved to work diligently during each timebox. I guess you can try the Pomodoro technique -- just remember that you can adjust the timings to whatever work best for you. I personally prefer the longer timeboxes (1.5-2 hours each).

This one small idea completely changed my life a few years ago. I always keep a list containing my next actions. If I find myself procrastinating, I don't even have to think, I just glance at the list and do whatever is on top.
