What is your ideal decluttering method?

You'd enjoy decluttering in multiple stages. Like doing a load of laundry, you'd start with prewash to treat stains and dirt, move on to main wash, and finish with a rinse cycle. Do a rough first decluttering of obvious and easy to spot clutter, either by category or by area, and then do a more thorough second run and so on until there is no more clutter. Take however long you'll need to finish decluttering.

You get overwhelmed with big projects. Stay away from massive decluttering projects. Instead, declutter little by little, one day, one drawer/box/shelf/cupboard at a time. Don't create a pile to sort through items. A pile of anything will overwhelm you. Instead, go through each drawer/box/shelf and what have you without taking things out. Declutter the easiest place to get a quick win which will give you the confidence to keep going. It's also a good idea to declutter what bugs you the most first, e.g., bloated medicine cabinet. Take as much time as you need to finish decluttering.

When you come up with an idea, you act on it quickly. You don't like making plans because you never follow through them. So when you get the urge to declutter, you don't wait to make a strategy--you just do it. There is nothing wrong with going with the flow. Just be careful not to throw out things you actually need and shop impulsively; otherwise, you will be trapped in a vicious circle of random decluttering.

The classic decluttering method promoted by likes of konmari. It will let you do a thorough decluttering in a relatively short amount of time (say under six months or so). You can tackle clutter by area or by category of items. Go through each item and ask yourself the following questions: Have I used this in the past year, six months or month? Did I even know that I had this? Does it add any value to my life? In what way? Does it make me happy to keep this? Does it reflect who I am today? Does it suit my current lifestyle? Would I keep it even if there were no one else in the world but myself? Sort items into piles of sell, donate, throw away, recycle, repair, belongs to other area in the house, undecided, etc. Don't buy any items to organise your stuff, e.g., containers, until you've finished decluttering.
