Switching to the "career of your dreams" is usually a bad idea I know several reasonably competent engineers and scientists who bankrupted themselves, and crippled their family finances, "pursuing a dream" of being a stay at home parent, pursing an artistic career and lost their engineering edge while they did it. They now regret the decision, but have no chance of recovering their engineering edge sufficiently to return to their original, much better paid fields. They'd have to start over as a 40 or 50 year old intern with obsolete skills, and there's no market for them.
If your dream is so important to you, fund it yourself as a hobby or a pasttime. I know too many reasonably competent engineers who blamed their lack of focus on their "lack of inspiration" on their lack of interest. They switched careers, and turned out to be as unfocused in their new "inspired" career. But because they were "unfocused" in a poorly funded career, they've either gone hideously broke or drained their family's finances finances supporting their career. I've known several who are literally a million dollars poorer between the loss of engineering income and with the educational costs of the career switch, for jobs they can't get because they're competing with much, much cheaper kids who are also dependent on family support to keep them fed. They spent their retirement funds and their kids' college funds on their "dream" careers, and they're pretty unhappy about it now.
Frankly, I see the same thing played out regularly for people who have doubts about their lovers or their spouses. They abandon decent, workable relationships in favor of their "soul mate" or someone else tempting who is "the one". If the alternative pastime, or alternative partner, is so ideally suited to you, let them work for it. Don't abandon your current working life or your current working relationship in favor of an unlikely dream. There are far too many broken careers, and broken hearts, from such switches.
Most simply put, I'll offer the advice that so many agents and editors give to their dreaming clients. "Don't quit your day job". If you turn out to be that good at your hobby, you'll find the opportunity to turn to it later as a full-time career. It's much less heart and wallet braking to work at your primary job and your primary relatonships. Just don't _lie_ about it, and over commit.
