At first I found it depressing and hard to 
eliminate cels out of my cel book...

but after a while you get 3 or 4 cel books 
mostly full of cels. and you realize that you 
don't look at ALL of them very much.  and then 
suddenly you realize if you sell 15 of the 
REALLY cheap ones you dont really like very 
much you can get one totally AWESOME 
dream cel.

I dont even shop that much right now for cels... 
becuase the ones I really really want are 
harder to find, so I'm just biding my time and 
attempting to save my money.

after a while it feels good to get rid of slightly 
lesser cels. I feel like overall by getting rid of 
the lesser ones, the overall impact of my 
collection is higher, at least for me. and I also 
feel less guilty about having so many cels. :)
