you know, i've only been collecting for a couple of years, and i was talking to a collector/businessman in florida the other day, and he had a excellant piece of advise that goes along with jen's quote above.
he said that the secret to staying in this hobby is to not burn yourself out, and be selective in what you buy, not having to purchase everything and need everything, he said that this hobby is like crack,(probably more costly) and is one of the most addicting hobbies that anyone could get hooked on.
maybe some of us may have to get out completely, but it'd be nicer if most of us could still be involved somehow, if only purchasing one or even two items a year, instead of 10-12. concentrate on the must haves, and that way you'll still have an interest, and that one or two must haves you get a year will only be that much sweeter.
