The "experts" on "hoarding" are often heard suggesting that - because presumably the person has "difficulty making decisions", "difficulty discarding", "emotional attachment" ( which I'm also questioning ) - whatever they recommend as "decluttering" should be done in small time stretches of, say 15 minutes - this is the figure often mentioned - and striving to increase that as one builds up stamina, or perhaps tolerance for the "bitter pill".
Now, let's do what I always recommend doing - stop, think, and ask questions.
Think of most activities you spend your time doing - your favorite hobby, your day job, playing with your kids, doing dishes, driving, etc. - do you need a 15 minute limit for any of that, or can you do it for hours on end, subject only to the general fatigue ?
If you can't stomach something for more than 15 minutes, I suggest that this is a sign that there is something wrong with the process, with what you're doing, or with the information you have about how to do it.
The process "experts" normally refer to, it seems to me, is a white-knuckled, teeth-gritting discarding in a chaotic, stressful, forced, limited situation, or inefficient efforts to organize things you chose to keep with insufficient space and bad organizing advice.
Let's forget all of that for a moment, and switch to "organizing your favorite things on your terms with no time pressure or requirement to discard anything whatsoever, with organizing structures that actually work".
How does that feel, now ?
You have carte blanche to keep anything, and to organize it any way you like, to set up as many containers and categories as you like, and discard only when you are good and ready ( say, once chaos has been reduced and the situation is much more on your terms ).
There is no stress, no pressure, no hard decisions at every step.
It really feels more like a hobby.
Do you think you still need a time limit for this, or can you do it all day just like those other regular things ?
Aha.
If you can't stomach something for more than 15 minutes, it's pretty likely you're doing it wrong or you don't have the right tools and resources.
Because when something is hard, there's often some non-obvious friction or other wrongness invovled.
These particular questions might be helpful -
* What am I doing, why am I doing it, should I be doing something different, should I be doing something else ?
* Am I discarding my things because someone else - an expert, a family member - insisted ? Does this make sense ?
* Should I focus on organizing things I intend to keep, if only temporarily until I have a better idea ?
* What Is The Sticking Point ( WISP ) / What Is The Frigging Friction ( WHIFF ) ? ( and aim to eliminate that )
Find and eliminate that to make the process easy and even pleasant and fun.
And it gets worse.
When you have the right process, and the work is flowing - interrupting that in such small increments is extremely counterproductive, it's really the worst idea ever.
See, there's this thing called "context switching" ( from computer terminology ) - starting a new task, or swtiching between tasks results in a certain "performance penaly", an "overhead" - you have to get in tune with the new task, and the context of being in tune with the previous task is lost. This would come out of the 15 minutes or whatever limit imposed, leaving considerably less for actual work.
So, does the 15 minute limit still make sense ?
Difficulty is likely a red flag that something isn't right - I suggest you look into reasons why.
