Why did she say that "she avoided her day jobs"? Since she is an author, if she has avoided her day job, which is writing, it doesn't make sense.

Here when she says "day jobs", she is not referring to her job of being an author, but she is referring to having a regular job with a schedule every day. Being an author is not a "day job" because you can work on your own time.
