I think I am! I dedicate so much time to proof-reading EVERYTHING (not just my writing, but letters, school work etc.) that I almost fail to get it done. I don’t profess to be perfect at grammar or punctuation - in fact - that’s the problem! I’m so insecure about making mistakes that I proof-read everything up to twenty times! Even once I’ve finished I spend time fretting over whether I missed something. I just worry that making a mistake will make me look unprofessional and unintelligent. As a result, I end up stressing about it and procrastinating. The three things that worry me the most are: Commas Tenses Syntax Syntax and commas worry me because their usage isn’t entirely dictated by any hard-and-fast rules. How you use them is partly down to how you want your sentence to sound. The reason I worry about tenses is that I’ve noticed that I have a tendency to use the wrong tense when the subject/verb is ambiguous. I never put a great deal of study into correct tenses and now I regret it. Are there any good online guides for the most common problems? I have a few guides at home, but they always word their explanations in a confusing way. I need something simpler. It’s annoying because the majority of the time I will spend five hours proof-reading a document and find mistakes that I could have spotted by reading it twice. For the most part, I don’t make terrible mistakes… I just worry about making them! Is there anyway to overcome this? I waste so much time!
