There are many different views about what minimalism is. Mine was: "defining your needs and striving to fulfil them fully by doing/getting as little as possible".
And the main benefit - for me minimalism was the thing that initiated the habit of finding out my true needs. More concretely - I think it can help somebody who has a list of favourite books to read, movies to watch, an elaborate todo list, a "Zettelkasten" notes system, but is somehow for some reason struggling with procrastination or burn out. In my case I think I tracked it down (as weird as it might seem) to my mind wanting/needing things which my body had no interest in and, in fact, was actively trying to get rid of.
The way minimalism helps with achieving that is quite straight forward - when you start stripping things down you are forced to decide what belongs and what must go. In order to decide you have to ask yourself - what am I really trying to achieve by owning this thing / doing this activity / writing this book / going to these meetings. Then you find out the real goal and gain clarity that allows you to pursue your goals directly.
1. This is just politics. 2. This is just marketing. 3. This is just boring/silly.
Presorting the feedback to the moderators and making you think before you flag. The third is just taste, but the first two are relevant to the hygiene of the platform.
The problem is that my flat is getting cold these days. I have not enough stuff to "keep" heat with inertia so I need to keep the radiator turned on during day and night. And that's pretty expensive (~€0.18/kWh).
That's my minimalist home!
