How close together do wake up times need to be to be beneficial? Is +/- 30 minutes sufficient, +/- 1 hour, etc?

Have you considered writing/self publishing some of your stories? Or even fictional short stories?

Could do amazon self publishing and see if you can make a few bucks.

Or even start a blog with some ads. Likely not as much money that route but probably lower commitment, as you can just write short posts rather than long stories. And if you can get a following can then try the book route.
