"Have less stuff" has been on the list for a while now. However, this year I've been reading up on minimalism and de-cluttering. The whole "less is more" really appeals. I'm also amazed how popular this stuff appears to be at the moment - or maybe its just that I'm more aware.
More to it than de-cluttering though. No point getting rid of things if you just go out and buy more stuff! So this year, a conscious decision to cut back on shopping. I don't need clothes, shoes, bags or house stuff. So unless it's broken or a real need my motto will be "use it up, wear it out, make it do or do without".
