One thing which I can highly recommend to anyone with motivation problems and help beat the procrastination is pomodoro technique [1]. When I'm stuck or can't make the first move to get into the work mood, I just hit the pomodoro timer. Somehow the ticking clock gives me boost and puts me into hours of productive work. Always! It's the only technique which works 100% in my case. Try it out for yourself.
Can't say enough about the pomodoro technique as well. I tried many things, this is what worked.
After training myself to work when the clock is ticking, I now find that clicking the "start" button on my timer triggers something in my brain that puts me to work. It's kind of trippy actually.
