To keep your inspiration, separate writing from proofreading. Write the whole draft first without stopping for mistakes, and check spelling, grammar, and logic afterwards, in a calmer moment.
You know the situation: you feel inspired, you have a great idea, and you just want to write it down. So you start typing, the words and sentences seem to appear in your mind by magic, and suddenly: wait, was it beautiful or beautyful?
You type both to see which one looks right, choose beautiful, and try to go on. Think. About. What. You. Were. Writing. And that's it: you have lost it.
When you are in the flow and your thoughts carry you through a fantastic article, stopping to correct a misspelling can break your mood in seconds. That can be really frustrating.
So why this instinct to stop and correct when you are so inspired? Why risk losing your concentration over a few misspellings? Isn't it far more important to say what you have in mind and get your thoughts across than to worry about an i or a y? Yes, it is.
So here is the tip: separate the creative writing process from the more rational proofreading process. Don't worry about small details until you have finished the big picture. Write your article, your story, or whatever you need to put into words, and only when your stream of thoughts and arguments has come to an end, step back and take a look.
Save proofreading for less inspired moments, when you can grab a cup of coffee, run a spell check, and correct all the spelling mistakes it finds. Then read the text again with a rational mind to see whether what you wrote really makes sense. You don't need to be inspired to do that. With the Spell Checker, it is easy to go over a text and decide calmly about each change.
In short, follow these steps.
1. Write
Type whatever is on your mind. Avoid the blank page syndrome that many writers know by simply writing down what crosses your mind. You will soon get into your thoughts, and your sentences and ideas will flow onto the page in one stream of consciousness. Don't interrupt yourself for small things while you are inspired.
2. Check the misspellings and typos
Finished with your creative moment? Then it is time to step back and start editing. You have captured the spirit; now you need to put it into a readable form. Start with a simple spell check: paste your text into a spell checker and look at its suggestions. Work through them one by one until you are done. This can be hard work, and you may need to stop and look up a word at any moment. But it is a focused process in which the creative part of your mind can rest.
3. Proofread for grammar
Do the same for grammar mistakes. Sometimes a grammar mistake is just a typo; sometimes it shows a gap in the logic of a sentence. Go over all the mistakes methodically, and you may refresh your grammar skills while you correct your text.
4. Proofread for logic
Once your text has passed the spelling and grammar checks, read it with a rational mind. Are there any logical gaps in the text? Does each sentence build on the ones before it, so that the reader can follow? Are the main ideas easy to understand without prior knowledge?
If you can answer all of this with a big, fat yes, you are done. For a full list of what to look at, see the proofreading checklist.
