Nearly everybody has an Achilles’ heel when it comes to writing…that one grammar rule you can’t remember without double-checking a grammar guide first, or that tough-to-spell word you have to check in the dictionary every time you write it (so you don’t look dumb). Some writers aren’t great with prepositions, yet they never confuse verb tenses, and other writers aren’t great with punctuation usage, but they never misspell any words, and so on. Such Achilles’ heels in writing are why writers prefer to rely on editors and proofreaders.
