An article* on shopping for clothes was posted by my friend recently and I thought some of it may be useful for teapot addicts. Here is a modified summary:
"The new rules of shopping should be something like this:
1. If there's only one thing you remember it should be: 'buy less, buy better'.
2. Don't buy now: research has shown that we get a lot of pleasure from thinking about something. Think like you've bought it. Often, by the time you've come to actually buy it, you're bored of it.
3. Never buy anything you like. Only buy things you love. Never buy anything that almost looks amazing. Only buy something that absolutely looks amazing. If you have an issue with even one little thing, don't buy it.
4. The first place to shop should always be your teapot cupboard.
5. Think of your teapot cupboard as an exclusive nightclub, where you are the doorman. Have a one in, one out rule. Decide on a maximum number, and stick to it. If you love something enough to want to let it in, decide who's not pretty enough to stay.
6. You're also the maitr'd: it's your responsibility to make sure the right people are sitting near the right people. That helps turn any clutter into a collection. "
