One of the best ways to check your writing is to read it out loud.
I realise your colleagues might not appreciate this technique if you work in an open-plan office, so you might need to step outside for a bit. But it’ll be worth it, I promise.
If you run out of breath while you’re speaking, your sentences are too long, and need a full stop or two. You’ll immediately hear if there’s a word missing, if it doesn’t flow well, or if something isn’t phrased quite right.
Reading it out loud forces you to engage with the text in an entirely different way, and all kinds of flaws will rise to the surface, despite the fact that you’ve read it silently several times.
Oh, and if you’re wondering if I read this out loud before I published, of course I did!
