I simply promised myself no more buying things I don't need. I even wrote a post on my own blog about what to do when you want things you don't need. And true to my pledge, I did not buy any clothes the past two years. I pledged to give away or dispose off something every day. And that has helped. Also, I have cleared up space by boxing up stuff we dont use , labelling them and and put them in the garage. I found that it is easy to give it all away from there. I also use the Facebook Freecycle group in our city to post stuff I want to give away. Works great.
