Different writers have different opinions on what you should hear when writing. Some will like a very quiet writing place with as little sound as possible; others will want instrumental music playing softly. Some writers even like the sound of a TV being on in the background. As long as what you can hear while you are writing should not distract you from the task of writing. Find what works for you, in particular, and do your best to remove any sounds that can distract you.
Write at the same time everyday. Set a schedule and stick to it. Doing this, you will find that you will start to automatically get into the online paper writer frame of mind at your scheduled writing time. Make sure you schedule breaks. Writing for more than two hours at a stretch will tire your mind and creativity. Breaks are very important in your writing schedule.
The only real difference between a professional writer and an amateur is that the Pro gets paid for their writing. If you get paid to write articles and blogs for Internet clients you are a professional. If you write them just to post them on your website and don't get paid you are an amateur. There are some amateur writers that can write even better than writers that get paid, so don't confuse the quality of writing with the status of amateur or professional.
