so maybe you do give up your phone? just have a phone at your house, people can leave a message.
we didn't have mobiles when I started work, even email was new and still used as a letter service.
now the phone goes 24/7, email is treated as a chat service, and I am less productive now than I was 30 years ago.
i currently have 500 unread emails, missed calls galore, and the world has ended. but I'm happier
