Clean my room and keep it that way

I no longer have a landlady the way I did back at the start of the year and as such there isn’t anyone that has any reason to complain about the state of my room.
On the other hand this room is at least 50% bigger than the two rooms I’d been in for the prior three and a bit years so I’ve got more space. Which my stuff has, to some extent, spread out to fill.
Getting rid of the old PC stuff would go a long way to making things tidier though. As would no longer just spreading bills, receipts, notices etc. across my desk.

I still need to vacuum regularly though.

I’m in a new place now and with it being a boarding situation there’s more motivation to keep the room tidy. I don’t want the landlady thinking I’m a slob, even if I am one.
