Huffington Post on the 13 Worst Cliches
"Clichés are the worst. Aside from being indicative of lazy speaking and lazy writing, they are rarely used correctly, and even when they are, they rarely make sense. Most popularized metaphors are outdated - who throws out bath water or sells tons of hotcakes anymore? Relying on such trite and nonsensical phrases shows an inability to discuss original thoughts or opinions, a.k.a. MAKES YOU UNBEARABLY BORING."
Don't be lazy with your writing. Keep it creative, fresh, new. Use your own voice.
