How do you spend time? productive?
After I retired I wanted to write a novel. I did that with voice recognition. I did some consulting via Skype. I wrote a chapter for a textbook. As the fatigue made long form writing more difficult, I wrote more short stories, and now poetry. My goal, such as it is, is to complete another collection (I wrote one years ago). I get an hour or two a day of reasonable clarity. Some days, though, I spend it farting around on the internet (ohai!).
