As a kid i was obsessed with Yugioh cards ( might still be, but whos asking? )
i used to anything and everything i could to get money from people just to be able to buy the next pack
when i finally turned 18 i sat down and wrote down everything that i had purchased ( including money from birthdays, christmas etc etc ) and i realized that it came out to over $5,000
needless to say I was done buying cards at that point....
haha wow 5k, i wonder how much i spent, though if you ask yourself how many hours you spent enjoying them in total, maybe it was worth it after all xD
