Mistakes always happen

It's a horrible feeling. You finally get your beautifully crafted brochure printed, and people start pointing out the typos. Why didn't you spot them before you went to press? You read it over and over again. You should have noticed them. The truth is, we read what we think we wrote, not what we actually wrote. That's why getting someone else to proofread for you is absolutely vital. Not only can they highlight the spelling mistakes, but they should also be able to tell you if you're not being as clear as you think you are. Hand your piece of writing over to a colleague, your partner, a friend - or the kids - and it'll save you pain later. If there's really no one to help, then put your writing away for a day, and look at it again with fresh eyes in the morning. (But DO NOT rely on your electronic spell and grammar checker!)
