Cleaning out is not easy.
Mainly because «Your decisions are tainted by the emotional investments you accumulate, and the more you invest in something the harder it becomes to abandon it.»
But somehow I managed to throw away almost 1\3 things I own. And it feels so much better since all those things "I will use some day. Maybe." are not on my mental and physical (from time to tome) shoulders anymore.
Surprisingly, cleaning out digital space was much easier (which I thought would be much more painful). It's quite a pleasure to unsubscribe from the news you've been deleting even without reading for months(!), delete documents you'll probably will never use again and materials you've been avoiding to read for years.
