I've "got rid" of stuff simply by buying less. As I've got older I don't feel the need to own as much stuff, and would rather spend my money on experiences. I've never bought a car (live in London), cycle most places, own a 2011 Macbook which I kind of want to upgrade but still does everything I need so it's hard to justify the outlay, and a PS4 and my dad's old TV. I think the most valuable possessions I have are my suits (3 reasonable suits worth about £300 each, so nothing too special there, and I need them daily for work). I don't feel like I'm missing out on anything at all.
