I never mince words when it comes to my opinion on checking your own writing, along with all business writing that represents you and your company. You or a trusted manager should review everything that leaves your building, whether it departs in an envelope, on a billboard, on video or virtually through electronic communication.
It’s always been important to illustrate your ideas in writing to make points clear. Can you picture a children’s book with no illustrations? And who hasn’t attended a business meeting or seminar where the uninspired (or inexperienced) presenter posted slides that he or she then read verbatim?
