One concept that you may want to consider is using your paying job in a way that works for you and fits your life goals. For some, this mean that the job is a way to get to what you really want, not a passion for its own sake.

For example, you may use your day job to get money to pay the bills and spend your free time pursuing your many passions. The requirement here is that your day job must allow you time off (mentally and physically) to pursue those other passions.

Or you get a job that will help you to develop skills that you can implement to pursue your passions (computer skills, perhaps). The requirement here is that your day job provides you opportunities to learn the skills you want to learn.

That said, even a job being used in this way should provide you with some sense of accomplishment. Life is way too short to spend 40 hours a week doing something you hate or that clashes with your fundamental principles.
