Hello,
  Well I really think a good idea is to sit back 
and reassess your priorities.  Do what you really 
want to do, in balance.  A lot of people who 
collect cels are often young with a lot of future 
expenses ahead of them.....car/house etc....and 
they tend to give up cel collecting once this 
time in their life comes up.  But cels are 
getting harder to get these days and in the 
future they will be very hard to find the 
rarer/better ones with all these CGI now.  I 
suggest you keep the cels you really love now and 
either have a break from collecting (don't look) 
for a while or be VERY SELECTIVE, with the plan 
that these cels you buy now/have now you want to 
keep for the long term, even make a financial 
limit if this helps, or a number of cels you'll 
buy in a year...
As time goes along, you'll find you'll be glad 
you kept those really special cels...after all 
you should do what really makes you happy...and 
if you're anything like me, despite all of life's 
ups and downs, cel collecting (within 
perspective) does make me happy.
  Good luck, Jennifer.
