I'm always on the look out for ways to clean up my room. I have a daily task on the todo list on my phone (Astrid) to throw/give away at least one item of my possessions. So that way even if I go for ages without cleaning up I'm still progressing, even if it's just one thing at a time.
In any case today and yesterday were more of the direct approach. I went crazy on my cupboards giving away clothes that I don't need and sorting out the various other things in my cupboards. You can see the before/after shots here:
It feels great to have a clean cupboard and although there's a few things still in there that don't need to be, it's great progress! I highly recommend cleaning your cupboard!
