Let me confess!
I used to be the messiest and the most chaotic f*ckhead you'd ever meet.
Lately, I began to learn how to tidy up - they say it helps with channeling one's aggression. Also, cleaning, sorting out unnecessary things, fixing the things in your environment adds some extra to your - even nonexistent - life quality.
I could never picture myself doing the vacuum cleaning and washing the floor every week - but now I am doing it. Of course I am not a masochist, I don't enjoy doing it - but existing in a clean environment certainly feels better and absolutely does worth the effort!
I began to get rid of things I never used, and it feels very special. It is easier to breathe.
Cleaning the bathroom is another thing I used to dislike. I still dislike it but I felt extremely ashamed of how the bathroom looked like. Forcing myself to clean it adds a little extra to my self-respect (pathetic, I know).
