> Even on your computer, log out of twitter, facebook and others. Only log in when you want to look into something... use private/incognito mode... use 2FA... it's an extra hurdle so you won't default to "quickly check"

Absolutely. Latest Firefox helps here. There's an option to use private by default for all windows. This means when you close it (another habit to develop perhaps) you don't stay logged in to these social media sites.
