You say you've gone into semi-retirement. What exactly does that mean? What is your basic day like now?
I wake up around noon. Watch TV all day. Eat bon bons. Around 7:00 p.m., I eat some fast food, then get all spiffied up and hit the local dance bars until 2:00 a.m. Wash, rinse and repeat.
Oh, wait. That was college.
I basically do the same thing as I did before, but freelance and on a project by project basis. A publisher will call me up and ask if I'm interested in managing a project. If I have the time and the interest, I take it on. If I hate the book or need a break, I pass.
I take the project from manuscript submission to press ready—sometimes doing the work myself, sometimes outsourcing it to other contacts. I do the same thing for self-publishers.
I mostly work from home, rather than at an office, although sometimes I'll go onsite for a project. Just depends on the needs of the project.
I don't really have a basic day. It changes depending on the project. If I'm not too busy, I get caught up here on these LDSP sites. If I miss posting here, or post late in the day, it's usually because I've got a deadline I'm rushing to meet.
