In general, a critique service focuses on content, while an editing service focuses on the technical side of writing (grammar, punctuation, and spelling.)

A few lessons from college writing courses, and advice from my HarperCollins editor, have stayed with me over time and greatly improved my writing. The first is strengthening verb usage, and the second is getting rid of unnecessary words/phrases. ​

No. The biggest mistake authors make is trying to rush the process. How do I know? Because I did it myself. We can’t seem to help ourselves. It’s just so exciting!
