64: The 7 Grammar Mistakes You Should Never Make


Listen Later

This week I’m sharing my 7 deadly sins of grammar. These are some of the mistakes you might be unknowingly making in your writing that’s causing you to lose credibility - especially online.

The goal of this episode is to give you more confidence in your writing. It is, after all, one of your most valuable currencies for intelligence. Proper grammar makes for good business, helps you command respect, and creates clarity in your message. 

The definition of grammar is the study of the way words are used to make sentences. This can be tricky because the grammar we use when we speak can be much different than the grammar we use when writing, but it’s always worth the effort.
