The trick is to be forced to quit.  I recently 
lost my job, so I was totally forced to knock 
collecting.  During the few months that I have 
been out of work I found it sort of nice to not 
be collecting.  My demeanor certainly improved, 
mainly due to getting rid of the stress related 
to the hobby.  ^_^  I think if you're serious 
about quitting, you have to really separate 
yourself from the community.  Plus....getting 
out of the house will help..you will see what 
all you're missing out on due to being so broke 
all the time from cels, haha.  I've got work 
now, so I plan on still collecting a tiny 
bit...but there is a LOT of things I want this 
year that arent cels.  So, I will be cutting 
waaaay back.  We'll see how long I can do 
it..but I have faith ^_^
