I have not been published yet but I have taken several writers classes and I can say this blog post is 100% correct. For example number item five in the article says (5. Don’t be afraid to outsource.)
As you can tell by my URL it is OdianTheWriter not OdianTheEditor.
I am not the best at editing my own work (story telling is more so my strong suit). So I have hired a very good editor to read over my novels, and I can tell you they are not cheap but if you get a good one it is well worth it.
Anyway if you or anyone you know is looking to get into writing I strongly suggest checking this link out. It really does help clear the water on what to expect on your journey to getting published.
