Only buy things that make your heart sing. If I don't love it, I won't buy it.
I tend to splurge on fancy dresses because I always think I'll get a lot of wear out of them, but it's false logic. You should really spend more money on the things you wear every day, like jeans.
I am selective. If I do splash out, it's an investment, and I wear things for years.
It's important to know when to take your time and not overspend and overdo things, of course. That's why you get things that can be dressed in a thousand different ways.
Frugality is founded on the principal that all riches have limits.
I'm not extravagant, so I won't need to rein it in too much. Me and my friend make each other cards. I love being creative and making things. But a better credit crunch idea is to not even bother sending cards.
My idea of splashing out would be buying a new spanner. I've got about 300 - you can't have too many in my opinion.
