I write during my lunch hour on a separate computer/physical journal while eating. In previous jobs I would "skill up" during every free moment like lunch, afternoon slump, extra time after completing something hard that day, etc while ensuring my job duties exceeded expectations. Sometimes I would build personal projects for my work that mimicked what I was doing outside of work so I could build the skill up and provide value at the same time. I typically look at any moonlighting rules for the company I work for and then keep those limitations in mind. Most are pretty lenient to say "don't use our resources and don't work on your stuff during our hours".
