I can't say I'm anything special but my onw advice would be to always carry a spare pair of socks because you never know!

One thing I do always have with my is a USB-C HDMI Dongle, HDMI Cable and Razer Raiju Android Controller though. This allows me to hook my Samsung Phone up to any TV (such as the big one at work or a hotel room) and play some emulated classics on the big screen via Dex mode.
