You’ve already invested a good deal of time in writing your book and now you’re tentatively thinking about the next steps. It can be highly tempting to skip the next stage – of getting your book proofread and possibly edited – because you’ve written it, you’re happy with it, you’re keen to get on with the production phase, and above all you want to save money. But this would be a mistake.
Indeed you may even think you can do your own book proofreading, but again this would be a mistake – you are too close to what you have written, you can’t be objective, and you read what you expect to appear on the page, rather than what you have actually written.
Requiring your manuscript to be proofread isn’t something to be ashamed of. All good writers, even long established ones with many published books behind them, have their books proofed and edited.
