It is very important to devote a significant amount of time to the editing process.
It is often suggested that a writer wait at least a couple of weeks before picking up their completed manuscript and reading through it with the goal correcting grammatical errors and making changes to the storyline as needed.
So, set aside a specific amount of time during which you can quietly sit with your manuscript, comb through it, and make the necessary changes. After using about three to seven days for editing, I would then have a trustworthy friend (one with excellent grammar and who enjoys reading) take a look at it and give me some honest feedback.
Of course, it is important to remember that when you later on choose a print-on-demand company to assist you with self-publishing, the company may offer editing services for a fee. But, if you'd rather save some money you can always depend on your own editing skills coupled with those of a close friend who has an affinity for language.
So, happy editing!
