It comes in waves. If you're not careful it gets obcessive and can be hard to control the compulsion with so many great bags out there.
It's happened to me a dozen times. Last time I "quit" it lasted several weeks.
For me it's not a feeling of zen so much as the horror that I've run out of closet space combined with the guilt that I've seriously over-indulged on purses in the past year.
Last Christmas I told myself that I have every bag I could seriously ever want. I have every bag that could make me happy. I promised myself I would not buy a single one this year except for a little something from the Cole Haan spring catalog, because surely there would be something I would like in the spring. Now that I've bought 2 bags from the spring Cole Haan catalog I'm back to feeling very guilty.
Being a Woman of a Certain Age I am haunted by the fear that one day after my demise my relatives will be cleaning up my house and they will gasp "Omigosh, look at all these purses! Who knew! She must have had some sort of psychological problem. It must have been serious too. Should we tell her husband?"
Really, when you get to be my age you worry about stuff like that. :s
