I watched an episode of Oprah with the topic compulsive hoarding. A woman filled her 3000 sq ft home (eerie, same kind of pic provided by barrister) with various stuff she has bought, collected, or items she said would be given as gifts. It took a team of 100 people eight weeks to organize the stuff (to be categorize as keep, sell, donate, trash) she had accumulated, and ultimately to clean up her home.
I saw this topic the morning after I watched that episode. Maybe the OP also saw that episode.
Mabuhay!
I guess, from this post, if you see your place/home/house is just like in the picture or something closer or worst, better fixed yourself first. Or at least if you feel/sense like you're starting to isolate yourself from other people or from participating in other activities, starting to neglect your responsibilities, again, go & see a doctor.
Anyway, for me, whether you're a collector, DVD addict, just a movie buff or a sucker for super sale like me or whatever you want to call it, at the end of the day the question is "does it make you a better/good person?" if the answer is YES, GO GO GO, you're in a healthy environment.
