I bet this is the norm for most of us, but I usually obsess over one particular stamp that I need for my collection. Daily checks of
ebay. Sometimes it might take a year or so for the stamp to show up. Invariably, once I obtain the stamp and that day of days arrives where it comes in the mail, I lovingly place it in the empty spot, admire it for about 15 seconds, and then I forget about it and never look twice at it almost (unless it's a notable stamp like a $5 Columbian, or Trans-Mississippi, Zeppelins etc. Right now I'm fixated on a US Scott #477. Need about 3 more issues to complete my Washington-Franklins. Of course the 3 remaining are 3 of the most costly.
