Freelance Writing Requires Skill, Persistence, Compromise and Sometimes Luck

Being a freelance writer is for many people, something to dream about. Dreams however, are rarely the same as reality. 
If you want to succeed, don't put too many restrictions on how you want to succeed. Many do, and that is often why they fail.
It is easy to think of stories to write, but writing them and getting them published is a completely different thing.
We make notes in our note book; scribble things down that we COULD write a book about. Most "paid" work for writers however, is not in writing books; nor is having a book idea the same as producing a manuscript that publishers really want to publish.
Putting that pen to paper or our fingers to the keyboard can be hard. for any new freelance writer; particularly if you are commissioned to write something you are not particularly passionate about; but often this is the only way to break into the profession.

Starting is always the hardest thing to do.
If you like to write it down in a note book – do that. If you like to type it first – do that. Try and get your thoughts down on paper.

When you start; Write for the Person Who Pays You
Too many new writers fail because they are writing for themselves instead of for the publisher or client.
It is important to give the person paying for your writing work what they want.  Publishers or employers who pay you to write will have a clear idea of what they want from you. They may specify the quantity (e.g. number of words), the message they want conveyed, and the date they want the work finished. A successful writer needs to be able to properly understand what is required, and maintain a strong focus on providing just that; being uninfluenced by any bias or prejudice.

Use Grammar and Punctuation Properly
Earlier we discussed the manner in which punctuation can improve the way in which your writing flows. Punctuation can do other things too. Punctuation can change meaning. Good grammar and punctuation is important in any writing, so ensure you are clear on grammatical rules. It is also important to check on the house style of the publisher or editor you are writing for to ensure you are clear on the rules they follow. For example, are they writing in American English or British English?  Do they write e.g., eg, e.g. or E.g.? Always check what is required.  

One thing that we often see in writing today is the use of exclamation marks! Some writers will put exclamation marks at the end of every sentence! Annoying! Appropriate! The use of exclamation marks can be appropriate.  If you are writing a teenage fiction novel, then exclamation marks may be appropriate:

“God, he’s hot!”
“Look at her dress. Yuk!”

However they should be used appropriately and sparingly in most cases. An exclamation mark can be used to emphasize a point, but a good writer should be able to do that without constant exclamation marks.  The occasional one is obviously appropriate: 

But not at the end of every sentence.

Choose to Create Clarity, or Confusion, With Intent. 
Sometimes it can be appropriate to be vague or ambiguous (consider a political speech), but at other times it is not. It is important to make sure that your writing is appropriate for the occasion. If you are trying to explain the greenhouse effect, an ambiguous, vague article will not do. A clear, concise, easily understood article will.

Be Logical, Organised and Systematic
Writing can be a job.  It may be your only job. It can be something you do as a hobby or part of your other job roles, but writing is still like any other job, so do your writing in a logical, systematic and organised way. Ensure that you keep your notes somewhere handy. Always carry a notebook around with you to write down ideas.  Keep your files in order. Ensure that you save any documents you are working on. Keep details of where you carried out research and so on. This may seem like an effort, but it can be frustrating three months later to think, “Where did I find that quote?”, or “Where was my notebook?”
