You have been writing ever since you learned your first letters. From writing a sentence in first grade to five page essays your senior year. It feels like your pen has never left the paper, and the reality of it is, is that it will not be leaving anytime soon. Most occupations will require you to write - whether it be an expense report or an e-mail, ergo, it would be in your best interest to be knowledgable of how to write well and all the rules that come along with that. Writing is and always will be important because you will always be writing, regardless of if you enjoy to or not.
With that being said, here are some key writing rules one should know about: punctuation, run on sentences, spelling, tense, and audience. These rules will become your best friend in the professional world when you are not just writing for a grade anymore. Even if you are writing something as simple as a birthday card, you should still follow the rules of writing and grammar.
To begin, punctuation is key when writing because it allows the author to express emotions within the writing. You must take caution when deciding which mark of punctuation to use because there are a variety of marks available. Without punctuation a sentence may say, "Do you want to eat Dad?" What you actually meant was, "Do you want to eat, Dad?" Without the comma the subject was eating the father, but with the comma the subject was asking the father a question. Both sentences had the same words, yet that small mark of punctuation made all the difference.
Along with punctuation comes run on sentences. Without punctuation the reader would not know when to pause and would just keep reading. Punctuation is key when avoiding that deep, dark path of run on sentences. Run on sentences are extremely unprofessional and confuse the reader. If you feel that your sentence may be too long, just add a comma where appropriate, or just turn the sentence into two sentences.
