I really like that phrase "voluntary simplicity". It takes away a lot of the negative connotation that these things usually have on people.
I've also always really wanted to do this, but time and time again I've proven I can't. I was very interested in the ideals of Buddhism for a month, I tried to start meditating everyday, I took daily walks just to watch the sky for a week or two - but every time I ended up finding something "better" to do with my time. "Better" as in, I could be leveling up in a game. That's a more efficient use of time, right? I hate it but I slip back into a mindset of being productive in a net-neutral or negative activity is "better" than simply taking time for an activity that is net-positive in the long run.
It doesn't help that I'm a fidget-y kind of person. I always need something to do, whether it is playing with my keys or playing with my iPhone. The iPhone has secured its spot, however, and it would be like quitting an addiction to keep that thing away for a day. Society as a whole is getting more and more afraid of living like this because of people like me, who don't feel like they can afford to take the time to live simpler.
Mad props to anyone who does this. I'd like tips.
