Writing ‘myself’ instead of ‘me’, or addressing others as ‘yourself’ puts up a subtle barrier between you and your reader – they know they’re being sold to. Badly. Same goes for any of those marketing buzz words that nobody uses in real life – verbs like ‘leverage’, ‘enable’ and ‘action’, for instance. There are very few sentences containing any of these words that wouldn’t work better if you replaced them with something simpler. Like ‘use’.
The point: Writing conversationally, even when it’s for business, doesn’t demean your writing. It helps you to communicate, that’s what it’s for. And it works too – would you really have read this far otherwise?
