My problem is that I am a die hard collector, first. It seems that many times I am buying a card for inventory, I get it and like it, and it goes into my collection. I guess it's not a bad problem but it's still a problem. I think what Barry said is fairly spot on. A possibe thing to do would be to keep your day job and practice the art of buying and selling on a small scale, to start with. See how that goes (it's not quite as easy as one would think, to make money) and then progress from there.....or not
. Good luck....
