Write with a Purpose

When you are first developing the main plot idea in your novel you may have an idea what the ending will be.  So then you need to fill in the storyline with details that will accomplish your purpose - getting to the end.
Writing with a purpose will help you to keep everything in order and keep you on track.  That doesn't mean what your write needs to be boring or predictable.  Writing with a purpose helps to focus on getting to the ending in an appropriate way. Leaving you plenty of room to add twists and turns in your literature writing.
Keeping our focus or purpose while writing helps keep everything cohesive and will allow our reader to enjoy our novel.  So what can be our purpose?
Type of Novels
If we are writing popular books such as science fiction or romance fiction remember to do proper research on details added to your story.  For science fiction it is good to consider your audience, they enjoy reading novels that are detailed enough so that it can be believable.  But making something believable means having a great imagination.  Romance fiction is always great if there is some drama but, again, it needs to be believable.
Not everything has to be a happy ending
When we write our novel considering your ending before you start will definitely keep you focused.  That being said we do not necessarily need to write a happy ending.  Possibly the main character has lost love, someone dies or if you want to write a sequel we could leave a cliff-hanger.  So depending on your purpose you will need to determine how the story will end.  Either all wrapped up in a perfect package or leaving your readers with more questions.
If you are considering a sequel or a series, then developing your characters is important. We want to keep our readers interested in each character.  We could have a series with each novel dedicated to a certain character.  Keeping our purpose in focus will enable us to develop one character's story while adding tidbits about the others so our readers will want to continue reading your future novels.  And as you write future novels you can add tidbits about previous characters to keep their story going.
Or you could write about one character who has different adventures in each new novel.  If that is your purpose then over the course of your novels you could introduce parts of the characters past that has developed their personality.  Or as different circumstances happen develops who they are or why they make certain decisions.
As you make a point to consider all the details in your novel take the time to see if they truly follow a clear line to your purpose.  Keep on track as you write, stopping from time to time to see if you are staying true to your purpose.  As you do this you will find the writing process enjoyable and will develop a novel that will be enjoyed by many.  Great literature has many good examples for us to learn from.  A good writer is a good reader.  Read novels and pay attention to how that author got from the beginning to the end.  Enjoy!
