We've been told to avoid cliches like...well, the plague.
Sometimes that can be difficult. After all, they are cliches for a reason - they give the image you want to portray. But not the tired feeling that may come with it.
I really wanted to use "like a hot knife through butter".
It became "like an Olympic diver piercing through water".
I'm still not completely satisfied and it will likely change before the edits are finished...but you can't say it is a cliche. Or at least not one I've heard of.
What cliches have you caught yourself trying to use. And what have you changed it to instead?
