Passion, drive, and existential fulfillment can take many form, and "professional joy" can absolutely be one of them.

It's not about drinking the corporate kool-aid, but about taking pride in what you've put in the world (even potentially as a hobby), having a sense of craftsmanship, or even maintaining a certain work ethic.

Even the "making money" part can be tied to a very deep sense of providing for your loved ones, and a sense of personal responsibility.
