Process for a writer
One thing that was very important to me when I first started writing (or to be more specific, when I got serious about it) was process.
I’m a software developer by trade, and process is extremely important. Each software development team from company to company will vary widely in its implementation of process. Whatever works best for each team (and each developer on it) is a factor that plays an important role in both the success as well as the experience of each developer.
