My first word of advice is KEEP THE DAY JOB!
The majority of those recognized names out there do magic more "on the side" than in the full-time profession many of us assume. The reasons are quite simple; it's darn hard to get a full enough schedule at decent per gig cash on a steady basis and it's even harder to manage those funds so they stretch. In my 30 years of doing this stuff I saw times when I was pulling in big money and working as many as five gigs a day and doing so steadily. Then again, I've seen those multiple years in which it was tough to just cover rent let alone a luxury item like food.
Show biz, in general, is a cold and unpredictable mistress; even with success on must pay a price. Typically this comes in the form of having close relationships, a family, or anything resembling "stability"; especially during those formative early years when you must hustle and push yourself on an 18+ hour a day, 7 day a week schedule. If you're not performing your selling (pushing to get the gigs).
Oh Yea! Just because you have a table hop gig locally that's covering your bills does not necessarily mean your a "Pro" in the greater sense of things. Each gig is just one part of a bigger pie -- a single stream of income. Even in the more traditional world we are in a situation in which multiple streams of income are required; when it comes to magic, that close-up gig must be your spring board to greater things -- private parties and corporate functions being the primary focus. Depending on what your personal goals are this could be kid/family oriented stuff (which isn't exactly the best income source at first; there is potential when you create a stage show that's "commercial"). . . understand too, the kind of facility you work in can set the tone when it comes to which markets are available to you; working at Chuck E. Cheese more or less insures that you are doomed to kiddie shows while a steady gig at Olive Garden or Red Lobster and open doors to the business and adult party venues.
Look at things from a business point of view NOT through the rose tinted lenses of a day dreamer. This IS A BUSINESS and if you don't approach it from day one as such, you're screwed! So learn how to be a businessman; marketing, salesmanship, bookkeeping/accounting, tax codes, investment making, etc. I emphasize this because in hind-sight, this area was my biggest weakness (still is) but is likewise the primary reason the majority of small businesses fail, especially in entertainment. Which takes us back to what I said in the opening; GET A DAY JOB AND KEEP IT! Unless you are able to generate the kind of income that will cover your life 110% don't give up that primary income source or, I should say, one or more key income generating areas of venture that are outside the sphere of "show biz" (and that doesn't mean writing 1001 eBooks, pooping out a new trick a month, or opening yet another on-line magic store selling the same exact stuff all the others sell).
I've run out of time to go into more, but this should give you plenty to think on
