One of the top stories I hear sounds like this: “I can’t push forward my ideas at work and no one listens to my opinion, so I decided that I need to revise some grammar”. I recognize the importance of grammar knowledge in communication and wouldn’t recommend that you never check the rules. However, we should remember that, first of all, grammar is about knowledge not about skills and secondly, to sell your ideas you should practice selling your ideas and address rules only if it prevents you from succeeding in your goal. It leads to my next question.
