Here's a weird, perhaps overly paranoid habit of mine: each year I arrive to Zabbix Summit -- or any similar conference -- with my Linux laptop reinstalled from scratch, running with the fortress that is Qubes OS. 

Thanks to that, no matter what would happen to my laptop either physically or through super skilled black hats, there's absolutely no risk that anything important or sensitive would be lost. It gives me the peace of mind and is a fun little period of time when I play around with something Completely Else.
