My advice for the new comic collector on what to do (and NOT to do):
1). Liquidating your home electronics and jewelry at Pawn shops is a no-no, UNLESS you have at least a full year of comic buying/selling under your belt AND you just made an impulse buy on a Buy-It-Now CGC 9.8 comic on ebay that you can't really afford.
2). Only sell your car to finance your collection IF:
a). Your work is not so far that you can't bike or walk there AND
b). You think that the money you're going to make on your comic collection will one day make up for all the girls who wouldn't give you the time of day because you were a car-less, comic-book collecting fanboy loser.
3). When attending the San Diego Comic Con, go to the unhappy-looking guy with all the expensive books near the main entrance (i.e. from where the Man of Steel hails), and say "Hi, I heard you were a royal h*le, could I have the 'special customer' discount please?"
4). Prioritize your monthly expenses: i.e., your comic book budget should always take precedence over things like deodorant, toilet paper (that's what fingers are for), utility bills, and secondary items like that.
5). And the last bit of advice I can offer: never take advice from a poster named JiveTurkeyMoFo.
