Don’t worry about mechanics at the start. If you worry about the mechanics or technical aspects of writing from the onset, you will most likely get bogged down and lose your trend of thought. What are the mechanics you shouldn’t worry about at the start? Spelling, punctuation, usage, sentence structure, and typographical errors. These are things that you can always go back to after you’ve put all your ideas down on the page. Many famous writers owe their editors for the polish and cleanness of their works. I even have it on good word that some popular writers can’t spell very well! What is important is to get the ideas written. Your ideas are what make your work original and interesting. Remember first and foremost that you are a writer and not a proofreader or an editor.
