One of the worst study habits that many students have is that of rushing to do an assignment. There are times when an assignment can be done hurriedly. These are really few and far between. There are also assignments which need a regular amount of time, almost daily. One of these assignments is a written paper.
Writing takes thought.
Very, very few people are able to sit down and write a good paper on the first try. It allows the writer to come back to the paper with a fresher ability to see the errors and to see the clarity of the thought. In other words, when you step away from your writing for a while, you will come back to it with a fresher mind. You will not be so deep into what you have written, and you will be able to see where a reader might not understand what you have written. Taking time to write, then pausing for a day or so, is one of the most beneficial steps you can take to create a good paper.
