I think effective communication is crucial, whether spoken or written. When you're speaking, it's your responsibility to ensure your message is delivered effectively and this holds true not only for salespeople but also for sales managers and company leaders. This is because what you say will be shared, forwarded, and copied, therefore, it's essential to craft a well-structured narrative. This way, your message can be easily understood in the moment and remembered when shared with others in your absence. Your written communication should also be compelling enough to sell your ideas when you're not present.
