There’s some good tips about travelling light and the kind of gear to buy, which trade-offs, to make, etc. in this guide. Interestingly, it’s from one of the founders of Ethereum, Vitalik Buterin. I’m not sure what I think of him, to be honest, but this guide is useful, nevertheless.
I have lived as a nomad for the last nine years, taking 360 flights travelling over 1.5 million kilometers (assuming flight paths are straight, ignoring layovers) during that time. During this time, I’ve considerably optimized the luggage I carry along with me: from a 60-liter shoulder bag with a separate laptop bag, to a 60-liter shoulder bag that can contain the laptop bag, and now to a 40-liter packpage that can contain the laptop bag along with all the supplies I need to live my life.
As a point of high-level organization, notice the bag-inside-a-bag structure. I have a T-shirt bag, an underwear bag, a sock bag, a toiletries bag, a dirty-laundry bag, a medicine bag, a laptop bag, and various small bags inside the inner compartment of my backpack, which all fit into a 40-liter Hynes Eagle backpack. This structure makes it easy to keep things organized.
As you might have noticed, a key ingredient in making this work is to be a USBC maximalist. You should strive to ensure that every single thing you buy is USBC-friendly. Your laptop, your phone, your toothbrush, everything. This ensures that you don’t need to carry any extra equipment beyond one charger and 1-2 charging cables. In the last ~3 years, it has become much easier to live the USBC maximalist life; enjoy it!
