I don’t really bother much in public places, I use umbrellas when it rains and sunglasses when it is sunny, but In general I try to avoid connecting to public WiFi and always use my vpn when I do.
I dont have any identifying data on my mailbox. I make sure to destroy PII on mail.
My routine is normal, gray, boring.
Do what you can and dont let perfect be the enemy of good. You’re still ahead of the rest of the crowd who don’t give a shit.
