New wardrobe

My plan was easy. I wanted to take a look into my wardrobe and decide what clothes I don't wear anymore. I spent about 30 minutes with it and I created two huge piles of unwanted clothes. I started selling it and three days after I went through the clothes that was still there. I tried few pieces on and I put them back in my closet. I am aware that I haven't worn most if for years but I somehow felt that I needed to keep it. Do you have the same problem or is it easy for you to get rid of old clothes? I didn't keep that much but I couldn't say goodbye to this dress (I wore it as a skirt). Maybe I will sell it one day....but not today. ...
