This has to do with the fact that we tend to invest emotionally into items we own. Therefore, our judgement on whether we need it and what it is actually worth becomes biased, and we’re more likely to hold onto something we don’t need.

A way of combating this is to play a three-step game, which psychologists believe will trick players into revealing how much they really need all the spare items in their home.

1) Look around the room and decide how much you would sell each item for.

2) Once everything has a price (we recommend writing them down), ask yourself how much you’d be willing to pay for the same object.

3) If you would be willing to sell something for a higher price than you would pay for it today, then you know you’re adding extra emotional value to something.

The difference in prices will show you how much extra baggage you’re keeping, and hopefully, it will inspire you to be a little more ruthless. Plus, it’s a tad more budget-friendly than hiring Kondo to come and work her magic.
