This is a really difficult one for me as I had tons and tons of papers everywhere! From upstairs to downstairs, from left to right!
Thank goodness I have a KonMari buddy, Ai Jou, who has been supportive and giving me advices when I needed it. I had to drill down the categories so as not to be too vague and be more meaningful to me. Luckily she had shared the below for my easy reference:
Back to papers, it's taking me a long time to de-clutter it. Example below, 1 of the plastic container filled with notebooks, stationeries and papers. So so so messy, having to categorise it accordingly is difficult as my space is limited. Well, it's filled with clutter hence the limited space LOL!
