Purging...

so I've spent a bit of time this weekend trying to clean and purge my bedroom and the rest of the apt by default as well. I have all kinds of ideas about what I want to do and what's the next step n my process. I have thrown or given away so much stuff in the last two years, and yet I feel like there's just so much crap around me right now, I don't know where to start. I want to re-arrange the living room and my bedroom. I want to paint. I want to class things up a bit, but wonder if it's worth it (the effort and the money) for all the improvement. At the same time I want to fix things up, I want to de-clutter and simplify. I have too much stuff. I don't need all of it, obviously. Where to start next. Hmmm...
