Editing needs to be done on paper

This past few days I have been editing a novel I've been working on.  I thought writing on a computer screen and using a spell and grammar check, that my work would be error free.  Then I decided to take the advice of others writers more successful than me and print it out and edit it with a red pen.

My, that red pen has been busy.  And you know what, as well as getting rid of all the mistakes I have made, I have improved the manuscript and re-written parts of it.

Editing on paper may seem laborious and old fashioned, but boy is it needed.  As writers we are so close to our work, we don't always see the mistakes.
