Open the nearest magazine, pamphlet or whatever and look at a random picture or a word.
Describe the picture or use that word as your starting point and write the first couple of sentences.
And then just keep writing.
Write whatever comes to mind and eventually, you'll get to a point where you'll be able to write about what you're supposed to.
Or take a few minutes and get some fresh air, clear your head and think about something else.
Sitting and blankly staring at your computer screen is useless, so you might as well go do laundry or maybe call a friend and go out for a cup of tea.
Doing something that will literally get you moving is usually the best way to go because you feel like you're actually doing something and it boosts you back into your usual productive self.
So cleaning your apartment, taking out the trash, doing a quick work out or taking your dog out for a walk are all good.
For me, the worst feeling is when at the end of the day I look around and see that besides not getting any work done, I'm also going to wake up to a messy apartment, with unwashed hair and not a gram closer to my goal weight.
You always hear people saying that something is better than nothing and if you ask us, that couldn't be more true.
