Do hope this week is better for you.
I am on a similar journey, but can only tackle it a couple of days a week, so I don't have your time limits. I think I am in this for the long haul...
I've picked up a lot of advice from these types of threads and it seems that each of us will relate to different ways of approaching the task. In case it helps, these are some methods which work or have worked for me.
Motivation, reading or posting on such threads or a YouTube clip before starting and sometimes during a session.
Grouping like items together, so I can see how many I have, work out how many I need and not keep the extra.
The permission to revisit a category. First time around, I may only be able to part with some of the excess, but in the future, I am more likely to be able to whittle the group down further.
Dana K White's container concept of fixing the size of the container into which a group of items must fit and adding items into the container in order of preference.
Reducing the size of the container on revisiting the category.
Ensuring that the category items are kept where you personally would first look for the item in question.
Not overfilling the container so it is easy to put things away. (This I really struggle with)
Stuff on which a decision has been made needs to leave the house asap so the decision is not revisited.
For me, no time or inclination to sell so charity shop, clothing bank or bin/tip.
Being more mindful of bringing in extra items into the house - a definite work in progress.
Questions I ask myself :
Do I know this to be useful or believe it to be beautiful? Wm Morris and Marie Kondo
If I needed this, where would I first look for it? Dana k White
Am I only holding onto it because it was a gift/inherited ? Clutterbug. NOT a good reason if not beautiful or useful.
When did I last use/wear it? (Reverse hanger trick is good for this)
Does it fit?
Would I want the DCs to see this and deal with it after we have gone? Swedish death clearance.
HTH someone else, but it has, at least given me the motivation to get on with the white ikea pull out wheeled draw today and find out what lurks in its depths.
