I had the pleasure of my landlord coming around recently so I had the usual panic of cleaning up and making my flat suitable for human habitation. In the past I've always told myself I'll keep the cleaning up but I never do so I've stopped promising myself. Thing is, having a clean flat is more than just being able to have people over with less than a week's notice. It genuinely does bring your whole mental state down when you live in a tip. When you have to say goodnight to a pig sty, then wave it goodbye as you leave for work in the morning only for it to still be there when you get back, it's just depressing.
So this time I've promised myself I'm going to keep my flat clean from now on :)
