A technique I have kept hearing from writers is 'never finish your last paragraph, leave it half written'.
The reason this works, is that when you start writing, a blank page can be an insurmountable hurdle to jump. But if you have half a sentence, half a paragraph already written, then you know where to start. You already have a plan for where to go... and by the time you get to the end of the paragraph, and into the blank void that lies beyond, you're writing, you're going, you've tapped into that bit of you which knows how to carry on.
The only hurdle you have to jump is overcoming your urge for completion.
You can do the same with many other problems : when cleaning a room, leave one shelf untidied so that you know where to start tidying... or when you finish one room move all your cleaning equipment to the next, so that its already there when you want to get started.
