Before I became minimalist, I was being a materialist; buying stuff that I actually don't need. I was being fun of buying new version of iphone, because i easily got bored on the old iphone, now i realized i was a slave to materialism. When I discovered meditation it changes my life, my brain frequency changes too, i became contented and grateful to what i have, all we have to do is change the way we think therefore changes our reality.
Brilliantly put cortexx, and the best part is this truth is liberating.
