It sounds like you've taken the first step: write. Nothing spurs ideas and keeps momentum building like putting words on the page or screen. If you're productive, it will help you no matter where your words end up or where your paycheck comes from.
That is a wonderful coincidence. I've been writing a novel too lately.
You have two options as you said: writing a novel and obtaining a writing career. By all odds, try both at once. Set a time daily to write your novel and then use the rest of your day for the writing career, eating, household jobs,and most likely your favorite thing: sleeping.
With a novel you need to keep a strong motivation running through your skull. You could potentially buy several books on how to write a novel, but in the end it must be instinct.
