You know how it is when you've been working on a paragraph/chapter/book so long you can quote it in your sleep, and you've lost all objectivity as to how it sounds and whether it makes sense. Sure, you could give it to someone else and let them take a look. Or you could put it in a draw and throw away the key for six months.
But if neither of those solutions are practical, here's two suggestions.
1) Change the font.
It sounds ridiculous, but it works. If you change the font of a block of text, it helps you look at it with fresh eyes, no matter how many times you've stared at it in the past. I usually work in TNR, and I find changing to Courier works wonders.
2) Listen to it read.
That doesn't mean you have to get someone to read it out to you (of course, if you have that luxury, that would be wonderful). There are plenty of free text-to-speech converters available on the web. They have very listenable voices, and can usually be adjusted to male or female, British or US etc. I paid $50 for the one I use, but that way I get full functionality - which means I can translate my entire book to an mp3, stick it on my ipod, and listen to it anywhere and anytime I like. Money well spent.
So there you go. Some tips I've picked up. Hopefully they'll be of some use!
Now excuse me while I dive back into the dark depths of Lake Edit. If only I could find my scuba gear.....
1 I've picked up so many useful tips from reading other people's blogs, I thought it must be my turn.
