You are stuck in your job. Enough is enough. The first thing you need is a muse to replace your income, so that you can leave your job.
If you think that way, your muse probably takes over the role of your job and you get stuck again. You don’t want to replace your job with a muse-job.
You want to replace your job with freedom. That means have a dreamline first. Then find a muse that fits your dreamline. The sequence of dreamline – muse helps you find motivation to finish your muse (or try another one if it doesn’t work out). Then, at last, you can quit your job.
