I really loved watching Tim Ferris's packing video five years ago when I first started traveling and ever since then have made my own. It's a great way to see what is actually needed, and get recommendations on what to bring and what to leave behind.
Here is my digital nomad lifestyle backpack, filled with everything I'll need as a location independent entrepreneur in Chiang Mai Thailand as well as Europe this summer.

Clothes: There's a new Uniqlo here in Chiang Mai which now allows me to buy quality clothes that actually fits my American frame. Bringing enough shorts and clothes for a year is no longer required. The only thing I would recommend to bring clothing wise is underwear and socks.
Bring your own shoes, especially if you have double wide feet like mine. For sandals I highly recommend Luna Mono sandals.
Bring your laptop. Get yourself either a Chromebook or a Macbook air. If you do a lot of reading, get a kindle. If you're going to do recording, bring a USB mic or two as a backup.
