I am nearly there I think. I started five years ago on a thread on here 'm' minimalism thread where I was due my first baby and stated to sort old cards and old bits and pieces.
I am at the point today (after watching kondo on netflix) that I had another boost and sorted things into categories. I now have a birthday box (candles, balloons spare cards all that) a lightbulb box with spares a homework box a stationary box. Etc etc.
I am naturally disorganised but I get things done. This is making my life easier. Sorting toys today (on annual leave)
My favourite thing is my label maker and plenty of see through bags
