Honestly, for me , it was basenotes. I always loved perfume, and had been spritzing from a young teenager, but finding this site turned me into an obsessive nutcase, literally from the very first thread!
When I discovered there was a world beyond "department" stores, I just couldn't get samples into this house fast enough. Day after day, reading about someone's new love or great "find" spurred me on! I did reach a point of saturation last year, when I realized I was ordering yet even more samples, without even trying out several of the scents I already had.
Happily though, I've finally come to a point of perfume passion, rather than the frenzied addiction which unmercifully took over my life for a couple of years. I am much more discerning now, and have come to really love and enjoy this strange obsession in a more calm and serene way.
So, this certainly will always be a passion and a great love of mine, and will forever be approached with ardent enthusiasm, but hopefully not with the excessive preoccupation of the past.
Basenotes, I salute you! You opened up a whole new world to me.
