I've read that too, but if it's worth firing off several unanswered emails, then it's worth a phone call. If it's not worth a phone call, then "cool your jets," and just wait for a response to your one email. You think that putting more into the inbox makes it's easier to get back to everyone?...again, completely "irrational."
Wearing the boots (almost) every day for nearly a year is a bad idea...unless you don't mind buying new shoes/soles regularly. Whoever said "wear the hell out of them. They're boots you idiot" gave you shxtty advice.
Yes, success means having a scheduled interview date and time. Without that, you've got a "maybe" at best. That's better than a "no," but it's still not a success. It's not a "bad" end to the interview, but it's not a great one either.
