One of the most important skills to acquire before you start writing is to know who will be reading your work. If you have to write a formal essay at school or college, or a report for your boss, the language and style should be concise and to the point. Minimum numbers of words should be utilized to make your points. If you are writing a novel and wish to engross an audience that will be in tune with everyday language and colloquialisms, you can be more expressive and utilize extensive descriptive sentences. Always remember your audience.
Although you may be fortunate enough to have the ability to structure your writing and retain a logical and sequential flow, you will still benefit from making notes. You should structure your writing under paragraph, sectional or chapter headings and under each one write keywords that will prompt you when you are actually doing the writing. If you are writing a story or novel, you will most often wish to follow a series of chronological events. If you are writing a school or college essay, you should follow a somewhat similar method by writing from the general and historical aspects to the recent and specific issues that you are addressing.
There can be a dichotomy between grammar and sentence construction and fluency and flow of ideas and thoughts. This may be especially true if you are writing as a second language user. One way in which you can overcome this is to make your notes and prepare your work without concerning yourself with the minutiae of grammatical correctness. Then, when your work is finished, review it for any technical errors that you may have made.
One method that some teachers find useful in writing preparation and practice is to form peer groups. One essence of writing that you should never overlook is that all writing is meant to be read. Therefore it will be explicitly or implicitly criticized. Especially for beginners to writing in a language, this criticism can be most positive if it comes from peers. In such a group, students will prepare and read or distribute their writing and the group will discuss it.
Writing skills are acquired. Your teacher can help you to acquire the technical and vocabulary skills associated with writing. She can also help you in areas such as paragraph construction and connectivity. But you must enhance these skills and the best way to do this for developing writing expertise is to read and note the styles and effects created by other writers. Reading is essential.
