How to whenever I buy sth new, I sell/throw out sth old
It made me
gooooood 
"it's so simple!"
How I did it: Every month I take sometime to go through my stuff. Like every month I go shopping. I look whats old or haven't worn at all.. I try to sell it second handed, if not it's for charity. That way I earn a little bit extra money and I can enjoy my stuff/space more. I've got a few huge piles of clothes waiting to get sold or give away to charity.
Lessons & tips: Look into that closet! What you have worn in a year you won't wear again so out.. try to sell it on ebay or on second hand markets that way you'll be updated and have more space for new things. You'll feel cleaner, relaxed and pleased.
