I find that one extra thing can get done per day. It might not be a very big thing, such as a few minutes spent on social media here and there during a brief break on a workday. More involved projects can get done during the weekend.
Yesterday I also set up my Amazon author page and did some social media. Today there’s this blog post.
This week is already filled, so I don’t know how much extra will get done. There’s an work deadline coming up, and a couple of meetings at the end of the week. Life is busy. Sometimes too busy. I’m not bored!
