I also make sure that any unnecessary radios are always properly off (not sleeping but really off). Bluetooth and NFC, and the usual updating....
I'm often travelling, and I don't trust the hotel wifi. Sometimes I carry a travel router as an extra point behind a vpn, probably unnecessary but it is handy for connecting multiple devices anyway. Otherwise, I prefer to use my own phone hotspot.
Multiple emails, with some disposable and a second SIM for disposable use (I have a dual sim phone). And time based 2 factor for critical accounts.
Despite all of this, probably a determined person could get through, but I guess not being the low hanging target is the best you can do...
Yeah I also tend to go quite far with these things :P If someone actually targets you specifically, they're going to get in no matter what (if they're smart enough).
Yep, probably via my wife or my kids....
