Yep its true! A person who writes any article that they are passionate about will become emotionally tied to the article and are then less likely to see mistakes.
A proofreader is detached from the work and is looking for errors (although if the manuscript is really good …………… well it can become difficult to concentrate ……………… so I concentrate on the job at hand the first time through and then read for enjoyment the second time. And I can still pick up changes in the second reading!!!!!!
So another tip is simply this – let a proofreader tell you on an unemotional level what changes can be made to improve your work.
Have a great day ……………..
