MINIMALISM
I read (I don't remember where anymore) that to let the important fill your life, you have to learn to get rid of the superfluous.
In my specific case, I am a declared disorder with many years of practice behind my back (my mother can corroborate this for her misfortune) but I managed to learn that order makes me feel very good.
If the order makes me feel good, why I don't actively seek it out?
I'm still processing it but I know it makes me feel good, and I know how to be tidy.
I am tidy when I have few objects. Maybe that's the explanation.
To grow is to accumulate objects and it is not easy to learn how to get rid of them and their meanings, but in my opinion, you have to try it.
Free space for your closets, drawers, shelves, and your mind.
How do I get started?
For me, the easiest way is to hide everything you haven't used in the last week and try to live like this. One more week, another...
And when a month has passed, everything you have NOT used should have a new destination.
Maybe it's a gift for someone who uses it more than you do or a donation to an institution that gives it a new use.
It's not easy to disown, so you'll probably fool yourself and get rid of just a few things, but you've already earned something.
I think the years in Singapore have been very positive to understand this just because there are no seasons. Wearing the same clothes all year round makes it much easier to understand which is more versatile and which is "very X but you never wear":
Back in a days in Spain I think I did something similar: I added more layers of clothes in winter (the sweater or the jacket) and changed the footwear, but most of the clothes that I "use effectively" were very little in relation to the number of clothes that filled my "what-ifs" wardrobe (what if it's rain, what if is too sunny, ect..).
Leaving the part of the clothes aside, something that happens when we accumulate too much "whatever" is that we end up not knowing what we have.
We have it, we know it's over there, in some drawer, but we don't use it because we've forgotten it. Doing these reviews of what we use for a month will give us a clear picture of what is important to us.
