As someone who just voluntarially went from a house, 3 cars, and tons of junk - down to what I can fit in my hatchback (including furniture) and a basic apartment, I can tell you that nothing is more liberating to me than throwing away / selling junk that I didn't need, and being able to live without stuff owning me.

Sure, my backpack has a nice laptop, iPad, etc. - but to me those are true conveniences. I've slept for years on shit mattresses, and I've come to conclude that it's how hard I worked that most affects my sleep.

Just my two cents...
