For the month of March, I am considering doing a shopping ban. There are other minimalists who have done this, and I think I should too. The concept of this is that you don't purchase anything besides toiletries, groceries, prescriptions (and other necessities). This won't be too big of a deal for me, because I hate clothes shopping, and I also don't buy a lot of "stuff" anymore.
The purpose of the shopping ban is to show how much "crap" we buy on a regular basis, and that we can also live without it. I will have to come up with some guidelines for my shopping ban, and this will come from reading other minimalist's versions of their shopping bans.
At the end of March I should have money in my pocket, a cleaner apartment, and a better appreciation for the stuff I have.
