Omnia mea mecum porto. – Cicero
Update 1 (2018): I am profiled in Rowan Hooper’s book, Superhuman.
Update 2 (2022): Both my bliefs and my circumstances have changed significantly since writing this post, and I no longer endorse some of the things I say below. The list of possessions at the end is now hopelessly out of date. Also, minimalism is more common now than it was back in 2014, so I don’t expect this to be as interesting as it may have been when it was first published.
All the stuff I own fits in a carry on backpack.
