My day job has declined to be the villain in my origin story

The fictional artist's resignation letter is beautiful. Their electricity provider has a less developed appreciation of narrative structure.

A day job can take time and attention. It can also fund materials and make a creative experiment less desperate to sell immediately. Both things can be true without a motivational podcast intervening.

Look at the arrangement you actually have. When are you able to make work? Which tasks leave you drained? Could a different schedule protect a regular block of attention? These questions are more useful than deciding whether employment makes you a legitimate artist.

Choose a project small enough to finish inside the available hours. That may mean a short series rather than a grand new practice announced to everyone you know.

If you want to change the arrangement, plan around your circumstances and obligations. Someone else's dramatic exit is not a timetable.

There is nothing cinematic about keeping the lights on. It does make it easier to see the thing you are making.
