Happy new year! And wow, you did a really great job cleaning up and decluttering! Your room looks so nice now.

And something important about me is that when my room is all messy, My own brain goes messy as well.

...me too!! I am totally the same, a cluttered/messy space makes a cluttered mind. Now I don't mind a "full" space - I actually like a lot of decorations and such around - but "clutter" where everything is a mess, yeah. It's like a short circuit to my brain.

I have to ask, though - where do you sleep? This is your bedroom, right?
