on Just Publishing Advice:
Every writer would like to have an editor
In a perfect world, having an editor to rely on would be your preference. But in reality, we know that the cost of hiring a professional is beyond the reach of the majority of writers.
There are many self-help, short story and fiction writers using self-publishing today. But it is unrealistic to think that all of them can afford to pay for someone to help in the writing and editing process.
But there is an expectation from readers that when they buy a book or even read a blog post or online news article, that the texts will be perfect.
If you read some of the major newspapers online, you will know that even with professional copy and line editors, mistakes still occur.
However, that is not an excuse. You should always be looking for ways to improve your writing, your grammar and style.
