I used to do game design as my hobby. Now I do game design as part of my job (programming and design), and that’s fun, but not as fun as it was before. Now, peoples lives are affected by whether I do a good job now (Eg, bad design -> failed game -> my friends at work lose their jobs). I also have to do it when I’m not in the mood as well, with strict deadlines.

I don’t want that to happen to my writing, which is purely enjoyable right now :)
