This is a common response I get. My best suggestion (for understanding) would be: just try, for an entire day day, to be phone and/or email -free. Bonus points for a typical workday replacement.

For the past nine years I've lived literally next door to my primary places of employement. I do bluecollar tradework, part-time (by appointment, only); I have very few clients, cultivated over years of firing bad clients. I show up, at planned times, complete jobs, go home.

I have an attorney who handles any legal contacts (my "registered agent"). Accountant handles tax BS.

My bank is adjacent to my neighborhood (since I cannot do online banking without text/email/2FA), so I just walk over for account transactions.

When a service "absolutely requires" an email (e.g. online gaming) I'll use a temporary email burner – with a corresponding online purchase (for any future account recovery needs, called-in).

In my city, most street parking is pay-by-phone. I can usually find a "free" spot, but this often takes a few extra minutes – my US city isn't huge so most stores have parking.

I do own a one-way pager; but it's been off for years. My family is essentially one other person, and is within visitable driving range.

Mostly I just don't like being interrupted/bothered (as much as I love socializing). Am honestly thinking about getting a landline... just to be able to "reach out" by voice, with a small whitelist.
