I spent today decluttering my room. What am I to do now?

I have a lot of extra time on my hand, so I decided to declutter and clean my room. I now have an extra plastic bag full of stuff that I threw out. I have a lot of those bags accumulated. I also have a lot of extra space in my closet after throwing a few clothes I have not used in years. So I now have all of this extra space and I don't what to put in it. What should I do? What does the average minimalist use their closet for? I don't have a lot of money to buy new things so I'm just being practical and I'm wondering what people do with their extra space in a minimalist lifestyle?
