I would just like to conduct a simple poll:
Since you do photography as a hobby or a profession, do you buy equipment because you really need it or do you buy equipment for the sake of having it?
How I would define Buying Illness (I think there is a better term for this):
A form of compulsion felt from within to acquire something EVEN IF ONE HAS NOT MONEY FOR IT, but WITHOUT being able to JUSTIFY LOGICALLY the NEED for the item. Compulsive buyer kinda thing. Of maybe the Buy Buy Buy attitude
Descriptive answers are most welcome... (I mean instead of just saying yes or no, write a para or two?)
