A few times now, people have set up a time and not shown at the last minute because they 'aren't ready'.
I know that all kinds of crazy things can come up before a recording and I'll give you a grace "do over" but after that I'll be far less inclined to do an interview with you in the future. I hope you understand that.
I value your time and I ask that you value mine by showing up on time and being ready to have an amazing interview with me. So please have the courtesy to choose a time and keep it...
