When writing web content, never publish anything until you have spell checked it and proof read it. It is easy to get in a rush and publish articles prematurely. One of the risks of of setting goals to publish a minimum number of articles each week is publishing poor quality content. If you are focusing too much on earning income, or building up a content library, it might leave your work mediocre, or at least not your personal best.
Writing should be enjoyed. Take your time and enjoy your writing experience. Cherish your work. Put the time and energy into it to make it quality content each and every time before hitting that publish button. If you do not finish it today, there is always tomorrow. Putting out quality writing will boost your reputation and make people want to read your work.
